I WANT TO ASK ONE THING THAT I HAVE DONE MY CLASS 12 PCB FROM CBSE WITH 85%. NOW I WANT CAHNGE MY STREAM AND I WANT TO PURSUE MECHANICAL ENGINEERING FROM ABROAD . THEREFORE SHOULD I PURSUE COMPLETE CLASS 12 PCM FOM NIOS OR SHOULD I GIVE ONLY ONE MATHS EXAM FROM NIOS.
Hello Jasan!
Mathematics is a basic requirement for Mechanical engineering, be it in India or abroad. So, it will be a basic requirement for you during your application to various universities abroad.
I will suggest taking the Board Examination for mathematics only through NIOS. This way you'll be able to add mathematics to your mark sheet. You do not need to PCM all again, appear only maths as an additional subject. This is because you already have a PCB mark sheet, and after appearing NIOS boards for maths, the marks will add to your mark sheet.
For studying in universities abroad, you have to qualify for SAT/ACT and language proficiency exams like IELTS/TOEFL. Go through the articles below to get more information about these exams in detail:-
