Do New Students always take exactly six IB subjects?

Most New Students in the full IB Diploma Programme take six subjects, and that is the standard structure schools build timetables around. The reason is philosophical as much as practical: the IB wants breadth across languages, humanities, sciences, and mathematics. Group 6 adds flexibility, because you can often choose an arts subject or replace it with an additional subject from another group. In rare cases, a school may allow an additional seventh subject, but it’s not the default and it can complicate your workload. For exam preparation, assume your revision system needs to support six subjects plus the core, because that is what most students will face. If you’re unsure what your school permits, confirm early so your choices don’t create surprises later.

How should New Students decide between HL and SL?

Start by checking whether your likely university courses have HL prerequisites, because that requirement is the one thing you cannot “revise your way around.” Next, look at your weekly time budget honestly, including sports, activities, and the core components. HL subjects usually demand more depth, more practice, and more resilience near exams, even when you enjoy the topic. Then consider grade strategy: a stable SL 7 can be more valuable than a struggling HL 5 if it protects your total points. Finally, test your choice with real practice: do a week of Study Notes, then a week of Questionbank sets, and see if you improve with effort. New Students who run this small experiment make calmer decisions because they’re using evidence, not anxiety.

Are TOK, EE, and CAS basically extra subjects for New Students?

In terms of time and attention, yes -- they often behave like extra subjects, even though they are not counted among the six. TOK asks you to write and speak with precision, which supports many exam responses across the diploma. The EE is a long project that teaches research and academic writing, but it also competes for time when other deadlines pile up. CAS is different because it is experiential and reflective, but it still requires consistent documentation and planning. New Students struggle when they treat the core as something to “deal with later,” because later arrives at the same time as mocks and internal deadlines. The healthiest approach is to schedule tiny weekly routines for the core from the beginning, so it never becomes a last-minute crisis. RevisionDojo’s tools (especially Grading tools, the Coursework Library, and tutors) help you keep the core manageable while you prepare for exams.

New Students: How Many IB Subjects Do You Take?

New Students Subject Selection IB

New Students arrive in the IB with a quiet fear: that there’s a hidden rule everyone else already knows.

It usually shows up the first time you look at your timetable and realize IB isn’t “pick what you like” -- it’s “build a balanced academic life… and then sit exams on it.”

So let’s answer the question cleanly: How many subjects do you need to take in the IB? And how do HL, SL, and the core components affect what you actually revise when exam season gets close?

The quick answer (and the checklist New Students need)

In the IB Diploma Programme, you normally take:

Six subjects total (chosen across the six IB subject groups)
Usually 3 Higher Level (HL) + 3 Standard Level (SL)
Plus the core components: TOK, EE, and CAS

If you want a fuller DP overview for New Students, this broader roadmap is helpful: The complete IB revision guide from subject selection to final exams.

The six IB subject groups (why it’s always six subjects)

The IB is built on breadth. That’s why New Students choose one subject from each group:

Group 1: Studies in Language and Literature
Group 2: Language Acquisition
Group 3: Individuals and Societies
Group 4: Sciences
Group 5: Mathematics
Group 6: The Arts (or a second subject from Groups 1--5)

That last line matters. If Group 6 doesn’t fit your goals, you can often swap it for an extra science, humanities, or language. If you’re deciding how to use Group 6 strategically, read: Is it better to take only one Group 6 subject or more?

New Students who feel stuck choosing subjects (especially with university still blurry) tend to benefit from this guide: Which subjects should I take at IB if I don’t know what to do in university yet?

HL vs SL: the part New Students underestimate

You still take six subjects, but not at the same depth.

Most students take three subjects at HL and three at SL. HL goes deeper and moves faster.

As a rule of thumb:

HL: about 240 teaching hours
SL: about 150 teaching hours

That difference becomes real in exam prep. HL often asks you to do the same skill, but with longer chains of reasoning, harder data, or more demanding evaluation.

If you want the simplest explanation of what changes between levels, start here: What’s the difference between HL and SL in IB? and then follow with: Does HL vs SL matter in IB? The honest answer.

Can you take 4 HLs (or 4 SLs)?

Some New Students hear rumors like “4 HL is more impressive” or “4 SL will be easier.” In reality, the IB allows some flexibility, but your school’s timetable and your workload limits matter.

One common question is whether you can design a diploma with 4 SL subjects. This guide explains what’s typically allowed and what’s risky: Can I take 4 SL subjects for the IBDP?.

TOK, EE, and CAS: the “extra subjects” nobody labels that way

New Students often plan revision time as if the IB is only six subjects. Then TOK deadlines appear, EE meetings land in the same week as a science IA, and CAS reflections quietly multiply.

The core is mandatory:

Theory of Knowledge (TOK)

TOK is your practice in thinking about how knowledge works. It can feel abstract until you realize it trains the exact skill IB examiners reward: clear claims, balanced evaluation, and structured explanation.

Extended Essay (EE)

The EE is a 4,000-word research project. It’s not “extra homework” -- it’s a long-term stamina test: planning, drafting, feedback, and revision.

Creativity, Activity, Service (CAS)

CAS isn’t graded, but it is required. It’s the IB reminding you that a life that only studies tends to break.

If you want to connect the core into one coherent system (instead of three separate stress streams), this is worth bookmarking: How RevisionDojo unifies reflection across TOK, CAS, and the Extended Essay.

A practical subject-picking lens for exam-focused New Students

When New Students ask “How many subjects do I need?” they’re also asking something more personal: “How do I pick a set I can actually score well in?”

Use this fast filter:

Match prerequisites first, preferences second

Some university pathways genuinely require certain HLs. Lock those in first. Then build the rest to protect your overall points.

Balance effort across the six subjects

You don’t need six “hard” subjects to prove anything. You need six subjects you can revise consistently.

Think about your exam-season system, not your ideal-self system

If your plan requires perfect motivation, it’s not a plan.

A useful reminder for New Students: you don’t have to study every topic equally to succeed. You need coverage plus targeted depth. This piece explains it well: Do you need to study every topic for IB?.

How RevisionDojo helps New Students turn six subjects into a plan

Six subjects is a lot. The difference between “overwhelmed” and “in control” is usually feedback and structure.

RevisionDojo is built for that reality:

Study Notes to get clear quickly without rewriting textbooks
Flashcards for daily active recall across all six subjects
Questionbank practice to turn understanding into marks
AI Chat when you’re stuck and need a clean explanation
Grading tools to improve essays and structured responses
Predicted Papers and Mock Exams to train timing under pressure
Coursework Library to understand expectations for internal work
Tutors when you need a human who can spot patterns fast

Closing: the calm truth for New Students

New Students don’t fail the IB because they took the “wrong number” of subjects. Almost everyone takes six subjects, then chooses HL and SL levels, then carries TOK, EE, and CAS alongside.

What separates students in exam season is simpler: having a repeatable system that works even when you’re tired. Build that system early with RevisionDojo’s Study Notes, Flashcards, Questionbank practice, AI Chat support, and timed Mock Exams. Six subjects stops feeling like a storm when you can measure progress in each one.
