Can You Change IB Subjects After Year 1? [Here’s What You Really Need to Know]

Introduction

Maybe the subject seemed interesting at first. Or maybe you needed it for a career path you’re no longer pursuing. Whatever the reason, you're now deep into the IB and wondering: Can you change IB subjects after Year 1?

Here’s the real answer—and how to do it without sabotaging your diploma or university goals.

Is It Possible to Change IB Subjects After Year 1?

Yes—but with limitations. The International Baccalaureate (IB) doesn’t officially prohibit changing subjects in Year 2, but most schools strongly discourage it due to time loss, IA deadlines, and exam preparations.

That said, with school approval, a solid reason, and a recovery plan, it can be done.

Typical Reasons for Switching Subjects

Students consider switching because of:

Academic struggles: consistently low grades or failing to grasp core concepts
Loss of interest: not connecting with the content
Change in university direction: needing a different subject to meet entry requirements
Mental health or stress: subject is too emotionally draining

When Changing Subjects Is Allowed

Most schools may permit changes if:

The request is made early in Year 2 (usually before October)
The new subject is available on the timetable
A teacher is available to support the transition
There’s a clear academic or personal reason

When Changing Subjects Is Not Allowed

Switching is rarely permitted when:

Too much time has passed (e.g., second term of Year 2)
The new subject’s IA cannot be completed on time
There’s no room in the schedule
The school lacks resources or staff
The student is already behind in other areas

Risks of Changing Subjects Late in the Program

Switching late can:

Put pressure on you to catch up a full year of content
Require starting a new Internal Assessment (IA) from scratch
Lead to weaker predicted grades in the new subject
Delay university applications if grades drop temporarily

It’s a serious decision and should not be taken lightly.

Subjects That Are Easier to Switch Into Mid-Program

Some subjects are more flexible than others:

Easier to switch into:

Group 3 (e.g., Psychology, Business, Global Politics)
Group 6 (Visual Arts, Film) if portfolios can be built quickly

Harder to switch into:

Group 4 Sciences (Biology, Chemistry, Physics) due to lab IAs
Group 5 (Math HL or AA) due to content intensity

What You Need Before Making a Switch

Approval from your IB coordinator or school principal
A detailed catch-up plan
Access to course materials and assessment guides
Tutoring or mentoring to fill knowledge gaps quickly

Impact on Internal Assessments and Extended Essay

If you switch:

Your old IA is discarded and a new IA must be completed
Your Extended Essay may need to change if it was tied to the old subject
TOK remains unaffected, unless you plan a subject-related example

Always clarify IA deadlines with your new subject teacher.

How It Affects Your University Applications

Switching can affect:

Predicted grades—teachers may not feel confident predicting a high mark in a subject you’ve just started
Entry prerequisites—switching out of a required subject could make you ineligible
Timing for reference letters or personal statements

Solution: Notify universities early and explain the change in context.

Can You Switch from HL to SL Instead?

Absolutely. This is a common and safer option. Many students:

Switch HL to SL if struggling academically
Use the freed-up time to focus on core components
Still meet university requirements (if no HL prerequisite)

However, you’ll need to add a different HL or adjust your subject balance accordingly.

How to Catch Up in a New Subject

Use summer or holiday time to read the Year 1 syllabus
Work with a RevisionDojo tutor or mentor
Create a weekly timeline to review missing topics
Focus on IA planning as early as possible
Practice past paper questions weekly

What to Do If Your School Denies the Switch

If switching is denied:

Look for ways to adapt within the subject
Focus on boosting IA quality and exam technique
Consider external support (like RevisionDojo) for tutoring, stress management, and motivation
