A few years ago, I asked a group of Grade 11 students in Singapore a simple question during a workshop: “Hands up if at least one of your HL subjects was influenced by what your friends were taking.”
Roughly two-thirds of the room raised their hands. A few laughed nervously. One girl said, quietly, “I think all three of mine were.”
I was not surprised. Peer influence is one of the strongest forces in a sixteen-year-old’s decision-making, and subject selection lands at precisely the age when belonging feels more urgent than almost anything else. Nobody wants to be the only one in their friend group sitting in a different Chemistry class. Nobody wants to eat lunch alone because their timetable no longer overlaps.
But here is what I have learned from watching hundreds of students go through the DP. The friendships survive different timetables. What does not survive is a student’s motivation when they are two terms into an HL subject they never actually wanted. This article is about how to make a decision that is genuinely your own — without becoming a social outcast, and without pretending peer pressure does not exist. Whether your friends are all queuing up for ib economics tuition or convinced that triple science HL is the only respectable route, you need a method that starts with you rather than with them.
Why Following Your Friends Feels So Reasonable
Let me be fair to the students who do this. Following friends is not stupid. It is a rational response to uncertainty.
When you have no idea what HL Physics actually involves, and your closest friend — who seems smart and confident — says they are taking it, their confidence becomes a substitute for your own research. You borrow their certainty. It feels safer than admitting you do not know.
There is also a genuine practical logic. Studying with friends is easier. You can share notes, compare IA drafts, revise together before exams. In Singapore, where students often live far from each other and commute long distances, having a study partner in the same class is convenient.
The problem is that these benefits are real but small, while the costs of a poorly matched subject are real and large. A study buddy might save you a few hours a month. A wrong HL subject can cost you two points on your final score and hundreds of hours of misery over two years. The maths does not favour the friend-based approach.
The Three Ways Peer Influence Distorts Subject Choices
1. The “Smart Group” Effect
In many Singapore schools, there is an unspoken hierarchy of subject combinations. Triple HL science plus Math AA HL sits at the top. Humanities-heavy combinations sit lower. Students who identify as part of the “smart group” feel pressure to take the top-tier combination regardless of whether it suits them.
I have worked with students who took HL Physics purely because dropping it felt like admitting they were not clever enough. They were plenty clever. They were just clever in ways HL Physics does not reward. Some later sought ib physics tuition and clawed their way to a 5 or 6 — but they would have scored a 7 in a subject that fit them naturally.
2. The Comfort Cluster
This is the opposite pattern. A group of friends collectively decides that a certain subject is “too hard” and avoids it together. Often the subject in question is Math AA HL or Chemistry HL. The group narrative becomes self-reinforcing: nobody in our circle takes that, so it must be unreasonable.
The student who quietly loves chemistry — who finds the ib chemistry data booklet genuinely interesting rather than intimidating — ends up taking it at SL to stay aligned with the group. They lose an HL slot in their strongest subject. Their friends never even realise the sacrifice was made.
3. The Single Influential Friend
Sometimes it is not a group at all. It is one person. A best friend, an older sibling’s friend, a classmate whose opinions carry disproportionate weight. This person says “Economics HL is boring” or “Biology HL is just memorising,” and the student absorbs that judgement as fact.
The trouble is that one person’s experience of a subject tells you almost nothing about how you will experience it. Biology HL is memorisation-heavy for students who approach it that way. For students who engage with the experimental and analytical side — who treat the ib biology data booklet as a tool for interpreting data rather than a list to memorise — it is a completely different subject.
A Self-Audit: Is This Choice Actually Yours?
Before you submit your subject form, run each HL choice through these five questions. Answer honestly. Nobody else needs to see your answers.
Question 1: If every one of my friends switched out of this subject tomorrow, would I still take it?
If the answer is anything other than a clear yes, you have found a peer-driven choice.
Question 2: Can I explain in two sentences why this subject fits my strengths — without mentioning anyone else?
Try it out loud. If you find yourself saying “well, my friend said…” you have your answer.
Question 3: Have I looked at an actual HL past paper for this subject, or am I relying on second-hand descriptions?
Second-hand descriptions are almost always filtered through someone else’s strengths and weaknesses.
Question 4: Does this subject connect to at least one university course I am genuinely considering?
If it connects to nothing you want, ask yourself why it is on your list.
Question 5: When I imagine sitting a three-hour final exam in this subject in November of Grade 12, do I feel capable or trapped?
Your imagination is not perfectly accurate, but it is surprisingly honest.
Tutor Insights: The Patterns Behind Peer-Driven Choices
Tutor observation: After working with hundreds of IB students in Singapore, one recurring pattern we observe is that peer-driven subject choices produce a distinctive grade profile: students score well in Grade 11 Term 1, when content is introductory and their friends’ enthusiasm carries them, then decline steadily from Term 2 onward. Self-driven choices show the opposite curve. Grades start modestly and climb as the student’s genuine interest deepens with the material.
Classroom observation: Students in peer-driven subjects tend to study with their friends but not effectively. Sessions turn into social time. Difficult questions get skipped by group consensus. Meanwhile, students who chose subjects independently more often study alone or with tutors, and their practice is more targeted. Those who sought structured ib biology tuition for a subject they personally chose, for instance, tend to arrive at sessions with specific questions rather than vague anxiety.
Score improvement pattern: When a student switches from a peer-driven HL to a self-chosen HL — even midway through Grade 11 — the improvement in that slot is typically two full grade points within a semester. The content gap is real, but the motivation gain more than compensates. We rarely see the same jump from simply “trying harder” in the original subject.
Hidden mistake: Students often assume the social cost of a different timetable is permanent. It is not. By Grade 12, most friend groups have reshuffled around IA deadlines, EE supervisors, and shared study habits anyway. The friends you started with in Grade 11 are rarely the exact group you revise with before finals.
Realistic Case Studies
Case Study 1: The Girl Who Almost Gave Up Chemistry
Student Profile: Rachel, Grade 10 student at a Singapore international school
Subjects Initially Planned: Biology HL, Economics HL, English A HL, Chemistry SL, Mathematics AA SL, Mandarin B SL
Initial Problem: Rachel’s four closest friends had decided as a group that Chemistry HL was “impossible” and were all taking it at SL or dropping it entirely. Rachel had scored the highest Chemistry grade in her IGCSE cohort and genuinely enjoyed the subject. But she had drafted a combination that kept Chemistry at SL so she could stay in the same classes as her friends. When I asked her to explain why Chemistry was at SL, she could not do it without referencing her friends.
Solution Implemented: We ran the five-question self-audit together. Rachel realised that Chemistry was the only subject on her list she would take regardless of what anyone else did. She moved Chemistry to HL and English A to SL — a swap that aligned better with her interest in pharmacology. She also began light pre-reading over the summer using the ib chemistry data booklet to familiarise herself with the HL scope.
Final Outcome: Rachel finished Grade 11 with a 7 in Chemistry HL — her highest grade. Her friendships survived. Two of her friends later admitted they wished they had kept Chemistry at HL themselves.
Case Study 2: The “Smart Group” Casualty
Student Profile: Arjun, Grade 11 student at a local Singapore school offering the IB
Subjects Taken: Physics HL, Chemistry HL, Mathematics AA HL, English A SL, Economics SL, Hindi B SL
Initial Problem: Arjun belonged to a high-achieving friend group where triple STEM HL was the default. He took it without much thought. By March of Grade 11, Physics HL was a 4, and he was spending most evenings on it while his Economics SL — a subject he found genuinely absorbing — sat neglected at a 6 that could easily have been a 7. He was exhausted and, in his words, “doing the IB for other people.”
Solution Implemented: Arjun’s school allowed a late switch. He dropped Physics to SL and moved Economics to HL. He kept Mathematics AA HL and Chemistry HL, which he was performing well in. He worked with a tutor on Economics essay technique and used the ib math data booklet more systematically to shore up the quantitative sections of Paper 3. For Physics SL, he leaned on the ib physics data booklet to reduce memorisation load and focused on securing a solid 6 rather than chasing a 7.
Final Outcome: Arjun finished with 41 points (7 Economics HL, 7 Math AA HL, 6 Chemistry HL). He was accepted to SMU Economics. His friends, all still in triple STEM, averaged 36. He remains close with them.
Case Study 3: The Boy Who Chose Alone and Thrived
Student Profile: Wei Jie, Grade 10 student at a Singapore international school
Subjects Taken: Geography HL, Economics HL, Mathematics AI HL, Biology SL, English A SL, Chinese B SL
Initial Problem: Wei Jie’s combination was unusual for his school. Almost nobody took Geography HL. His friends teased him about it. His parents were sceptical of Math AI HL, having heard it was “the easy math.” Wei Jie had researched urban planning and environmental policy degrees carefully and knew this combination fit both his interests and the entry requirements for his target courses.
Solution Implemented: No academic intervention was needed. What Wei Jie needed was reassurance that his reasoning was sound — and a plan for handling the social friction. We scripted a simple response he could use when questioned: “I looked at the courses I want to study and worked backward.” He said it enough times that people stopped asking.
Final Outcome: Wei Jie scored 42 points with 7s in Geography HL and Economics HL. He received offers from UCL and NUS for urban planning programmes. He was, by a wide margin, the highest scorer in his friend group.
Peer-Driven vs Self-Driven Choices: A Comparison
| Dimension | Peer-Driven Choice | Self-Driven Choice |
| Grade 11 Term 1 performance | Often strong (social momentum) | Often moderate (adjusting to HL) |
| Grade 12 performance | Frequently declines | Frequently climbs |
| Study session quality | Social, unfocused | Targeted, question-driven |
| Response to setbacks | Blame the subject, disengage | Adjust methods, persist |
| IA engagement | Topic chosen for convenience | Topic chosen from genuine curiosity |
| Typical HL grade range | 4–5 | 6–7 |
| University alignment | Accidental at best | Deliberate |
A Decision Matrix You Can Actually Use
Scoring your options removes some of the emotion from the choice. For each HL subject you are considering, rate it from 1 to 5 on the criteria below, then total the score.
| Criterion | What to Assess | Weight |
| Genuine interest | Would you read about this subject if nobody assigned it? | ×2 |
| Demonstrated aptitude | Past grades and ease of understanding, not just marks | ×2 |
| University relevance | Does it appear in the requirements for your target courses? | ×2 |
| Assessment fit | Does the exam format (essays, calculations, data) suit how you think? | ×1 |
| Workload compatibility | Can you sustain this alongside your CCA and other HLs? | ×1 |
| Independence of choice | Would you still pick it if all your friends dropped it? | ×2 |
A subject scoring below 30 out of 50 should be treated with suspicion. A subject scoring above 40 is a strong HL candidate regardless of what anyone around you is doing.
Handling the Social Side Without Losing Friends
Choosing independently does not mean isolating yourself. It means being clear with yourself first, then managing the social fallout with a bit of tact. Here is what has worked for students I have coached.
Decide before you discuss. Do your research and complete the self-audit privately. Once you know your reasoning, group conversations become far less destabilising. You are sharing a decision, not seeking permission.
Have a short, honest script. Something like “I looked at the courses I want and picked what fits” ends most conversations. You do not owe anyone a defence.
Offer alternatives to shared classes. Suggest revising together for the SL subjects you do share, or studying in the same library at the same time even if the content differs. Proximity does not require identical timetables.
Expect the teasing to fade. It always does. By the time IA deadlines hit in Grade 11 Semester 2, nobody has the energy to care what anyone else is studying.
Notice who supports you. The friends who respect an independent decision are the ones worth keeping close through the DP anyway.
Common Ways Students Fool Themselves
| Self-Deception | What It Sounds Like | The Honest Version |
| Convenience disguised as strategy | “We can study together, so it’s efficient” | You want company, not efficiency |
| Prestige disguised as ambition | “Triple science keeps my options open” | You have no intention of studying science at university |
| Fear disguised as realism | “Math AA HL is too hard for anyone” | Your friends said so; you never checked |
| Loyalty disguised as logic | “It would be weird to be the only one in a different class” | Weird for about three weeks |
| Deference disguised as respect | “My friend knows more about this than I do” | Your friend knows more about their strengths, not yours |
Your Action Plan for the Next Two Weeks
- Run the five-question self-audit on every HL choice tonight. Write the answers down. Any subject that fails Question 1 goes back under review.
- Complete the decision matrix for at least five candidate subjects. Include one or two you have not seriously considered. The results sometimes surprise students.
- Attempt one HL past paper question set in your top three choices — alone. Not with friends. Not with a tutor. Just you, a timer, and the paper. Note how each one makes you feel.
- Draft your two-sentence explanation for each HL. If you cannot write it without referencing another person, the choice is not yet yours.
- Tell your closest friend your decision after you have made it, not before. Watch how it feels to say it out loud. Confidence in that moment is a good sign. Dread is information too.
Your friends are not choosing your subjects with bad intentions. They are choosing their own, with their own strengths, goals, and fears. The mistake is assuming their map works for your terrain.
Two years from now, when the results come out in July, nobody will remember who sat in which class. They will remember the score. Make sure it belongs to a combination you chose for yourself.
