CBSE 12th

You are advised to seek admission in B.Sc Hons Maths or BStats to pursue your interests in Math. You may also evaluate doing B.Tech Computational Maths.

Both Medical and Engineering are equally good career options. You must choose any based on your interests to excel as a professional.

No. Go for engineering only if you are very interested in it. There is a very saturation in this field.

Dear Joshua, you should be able to pursue, you also need to be specific with your gap.Work experience gained would be vital. Otherwise your profile is alright.Take your IELTS too.

Dear Kriti,
Nobody can and will tell you dates for exams you need to appear. Specifying a date won't guarantee full marks as well. Nobody on the other side of this app can know about your preparation strategy, your calibre etc. The best we could do is to suggest you to keep atleast 9 months ahead of the application dates Around 3-5 months would be required for preparation of each test. During March to August should ideally be your test date.

Hey Himanshu,
It's very important for you to go with your interest. You can go for LLB (Hons). It's takes little time but once you are done you can get many doors opened further.
Good luck Himanshu.
