One of the most important steps in starting your IB Diploma Programme (IBDP) journey is deciding which subjects to take at Higher Level (HL) and which at Standard Level (SL).
Your HL and SL subject choices determine not only your workload and learning experience but also play a major role in university admissions and future career paths.
At Advika Institute of Education Pvt Ltd, we help students navigate this crucial decision with clarity and confidence — ensuring that every choice aligns with their academic goals and personal strengths.
In the IB Diploma, students select six subjects — three at Higher Level (HL) and three at Standard Level (SL).
Here’s the key difference:
| Level | Study Depth | Teaching Hours | Assessment |
|---|---|---|---|
| Higher Level (HL) | In-depth exploration of topics, more complex analysis | ~240 hours | Additional coursework, papers, and internal assessments |
| Standard Level (SL) | Broader overview of subjects with less content depth | ~150 hours | Fewer assessment components |
While both HL and SL are equally valued, HL subjects show a stronger level of mastery and are often preferred by universities for specific programs.
Most universities — especially in the US, UK, Canada, and Europe — pay close attention to your HL subjects because they reflect your academic strengths.
For example:
Engineering applicants should take HL Mathematics (AA) and HL Physics.
Medical aspirants often choose HL Biology and HL Chemistry.
Business or Economics students benefit from HL Economics and HL Math.
Humanities students may opt for HL English, HL Psychology, or HL History.
In short, your HL subjects should align with the field you plan to pursue at university.
Pick HL subjects in areas you enjoy and perform well in.
Since HL courses go deeper and demand more time, choosing subjects you’re naturally good at makes them easier to handle.
Ask yourself:
Which subjects have I consistently scored well in?
Which topics do I find most interesting or fulfilling?
Research your desired degree programs early.
Different courses have specific subject requirements. For example:
Architecture → HL Visual Arts or HL Math
Computer Science → HL Math and HL Computer Science
Law → HL English, HL History
Medicine → HL Biology, HL Chemistry
Choosing the right HL subjects now can open more university doors later.
Remember, the IB Diploma is a marathon, not a sprint.
While enthusiasm is great, taking three heavy HLs (like Math, Physics, and Chemistry) can be challenging without proper balance.
Tips:
Mix analytical subjects (Math, Science) with creative or essay-based ones (English, Psychology, Visual Arts).
Consider your extracurricular load and CAS commitments before finalizing your HLs.
You’ll spend two years studying these subjects, so motivation is key.
A subject you enjoy will always feel easier — even if it’s demanding.
HL subjects often include independent projects or extended research, which become more enjoyable when you’re genuinely interested in the topic.
Here are a few popular IB subject combinations for inspiration:
HL: Mathematics (AA), Physics, Chemistry
SL: English, Economics, Language B
HL: Economics, Business Management, Mathematics (AI or AA)
SL: English, ESS, Language B
HL: English, Psychology, History
SL: Math (AI), Language B, ESS
HL: Visual Arts, English, Psychology
SL: Math (AI), ESS, Language B
Start exploring early: Review subject syllabi and sample assessments before you choose.
Seek guidance: Talk to teachers or IB coordinators to understand your strengths.
Think long-term: Keep your university and career aspirations in mind.
Stay flexible: If a subject doesn’t suit your strengths, discuss switching options early in the term.
Maintain balance: Three HLs are mandatory — pick a combination that challenges you, but also allows you to succeed.
Your HL and SL subject decisions define your IB experience and academic future. The right mix helps you stay motivated, manage your workload effectively, and meet university requirements with confidence.
