Hi

I am guessing that it is about class 10th CBSE board.

Yes, you can definitely choose Biology for your 10 + 2 in science stream even if you take  standard maths in your class 10th .

The additional benefit of choosing standard maths is you are always free to choose maths for your 10 + 2

In 10th cbse board, there are 2 options for maths.

----------) Standard maths : - it is for those who want to study  maths after 10th like those who wants to have science with MATHS i. e PCM for 11th and 12th.

----------) Basic maths :- it is for those who don't want to study maths after 10th like those who wants to science with Biology i. e PCB,  commerce, arts etc in 10+2.

To help you further,

Here are the options after 10th :-

* 10+ 2  :-

You have to choose any one of science  Commerce , Arts/Humanities streams.

---------)Science :-The science stream can be further divided into 3 groups depending upon the subjects one chooses

****** Non medical :- Science with PCM i.e physics, chemistry , maths group. There's no biology in PCM group.

You should basically choose this if you want to pursue engineering/architecture etc in future.

****** Medical :- Science with PCB i.e  physics, chemistry biology.

You should choose PCB group if you want to get into medical field like mbbs, bds, nursing etc in future .

****** PCMB :- You can even go for science with PCMB i.e physics Chemistry Maths and Biology  if you are interested in studying both Maths and Biology in your 10+2. But yes, it becomes a bit difficult to handle both biology and Maths. One advantage of choosing pcmb is after 10+2 you can go for both medical courses like MBBS, bams, nursing etc and non medical courses like engineering as well.

-----------)Commerce :- You get to study subjects like Accounts, Business studies, Economics & Maths ,Commerce etc. If you want to become a chartered accountant, company secretary, financial advisor etc in future, then commerce is for you. In commerce you acquire commercial knowledge required for business.

------------)Arts :- If you like subjects like history, polity etc then you can go for Arts. You get to study subjects like History, Geography, Literature, Political Science, economics etc. You should go for arts if you aspire to get into Journalism, literature,languages, history, psychology etc.

****** Polytechnic / Diploma in engineering  :- After   your 10th you can go for diploma courses in various branches of Engineering like mechanical, Electrical, Civil etc on the basis of your interest.

****** ITI :- ITI is a skill development course which you can go for after your 10th , you can do iti any trade of your choice like Electrician, fitter, Welder etc.

****** Paramedical courses :- after your 10th you can go for various paramedical courses for which you can get detailed information at https://medicine.careers360.com/articles/paramedical-courses-after-10th-12th
