Choose IGCSE or ICSE subjects at the end of Class 8 by working backwards from Class 11: decide which streams, boards and fields should still be possible two years from now, and keep every subject those paths need. The choice looks small. It is the first decision in school that can close a door, and it is made at 13 or 14, well before a CBSE student faces anything like it.
Why this choice comes early
A CBSE student studies largely the same set of subjects until Class 10 and chooses a stream only in Class 11. IGCSE and ICSE students choose part of their subject list for Classes 9 and 10 (Grades 9 and 10). A subject dropped at this point is hard to pick up again, and some Class 11 options depend on it.
Most families make the choice in a few days, from a form the school sends home. It deserves more time than that.
How IGCSE subjects work
- The list is long, the school’s list is short. Cambridge offers over 70 IGCSE subjects, and schools can offer them in any combination. Each school teaches only part of that list, so the real choice is what your school offers. Source: Cambridge International, IGCSE curriculum. Checked in October 2026.
- Core or Extended. In many subjects there is a choice between a core and an extended curriculum (Cambridge International). Ask the school which one your child will be entered for, in Mathematics and the sciences above all. The extended course covers more, and it is the usual base for the same subject in the IB Diploma or at A Level.
- Separate or combined science. Some schools offer Physics, Chemistry and Biology as three subjects and also a combined science course. A student who may take the Science stream, the IB sciences or A Level sciences later should take the three separate subjects where the school allows it.
- English and a second language. Check which English course the school enters students for, and keep a second language if the next school or board will ask for one.
How ICSE subjects work
ICSE subjects are arranged in groups: one group that every student takes and groups from which the student chooses. The exact lists, and how many subjects must be taken from each group, are set out in the CISCE regulations for the year of the examination. Read the regulations for your child’s examination year on the CISCE website, and ask the school which of those subjects it teaches.
Two points matter more than the rest. Mathematics and Science sit among the subjects a student chooses, so it is possible to finish Class 10 without one of them. And the applied subjects, such as Computer Applications, Economic Applications, Art or Physical Education, are a real choice between quite different directions. Both decisions shape what is possible in Class 11.
The subjects that keep doors open
- Mathematics. Needed for the Science stream, engineering, computer science, economics and most of commerce and finance. Keep it, at the highest level the school offers, unless there is a clear reason not to.
- The sciences. Physics, Chemistry and Biology together keep both engineering and medicine possible. Dropping one of them at 14 decides that question too early.
- One subject from the humanities or commerce. Economics, History, Geography or Business Studies. This is how a student finds out whether those fields interest them.
- One subject chosen for interest. Art and Design, Computer Science, a language, music. For design and architecture a portfolio begins here.
A student does not need a career plan at 14. They need a list of subjects that leaves the two or three likely directions open.
What comes after Class 10
After IGCSE or ICSE a student moves to ISC, CBSE, the IB Diploma or A Levels. Each of them builds on the Class 10 subjects in its own way. The IB asks for subjects at set levels; see our guide to IB subject choices. A Levels are a small number of subjects studied in depth, so each one needs a sound base from IGCSE. The Science stream in ISC or CBSE needs Mathematics and Science from Class 10.
If the family may change board after Class 10, or is weighing India against study abroad, decide that first. The subject choice follows from it. See school and board selection.
Five mistakes we see
- Dropping Mathematics or a science because of Class 8 marks. Marks at 13 say little about ability at 16. Find out why the marks are low before giving up the subject.
- Taking combined science to lighten the load. It can leave a student short of what the Science stream or the IB sciences expect.
- Choosing with friends, or for a teacher. Friends change sections and teachers change schools. The subject stays.
- Choosing what looks scoring. A high grade in a subject no later course asks for is worth less than a good grade in one that is required.
- Choosing without knowing the student. Interests, aptitude and the way a student likes to work can be assessed. Guessing is not necessary.
When to ask for advice
For most students we advise starting career counselling in Class 9. IGCSE and ICSE students are the exception: they need a first conversation at the end of Class 8, before the subject form is filled in. More on timing in our guide on when career counselling should start.
How we help
At Global Careers the process starts with the Career Fit assessment, which looks at interests, aptitude and work style. Dr. Manish Mittal and his team check the results with the student in person, and the family meets Dr. Manish Mittal and his team. We then set the subject list against the streams, boards and courses the student may want later. See stream selection in Grades 9 and 10.
