CBSE 10th

Hi, I would suggest you to reappear your class10th and complete your 10+2, as this is the base for all career oriented courses like Diploma or Degree courses. There are many business-related courses but not for below 10+2 level.
So think about it and all the best.

It will be decided in the counseling according to your choice of branch if your marks are good.

You would be getting 8/10 in both 10th & 12th rating score for calculation of application rating. Hence, you cannot afford to loose a single score in application rating to even get a call from IIM A. Hence, try hard to get 10/10 in Bachelor's degree which would translate to 85%+ score in case you are an engineer or somewhat less in other streams. In terms of CAT percentile, by thumbs up rule, you would need more than 99.7- 99.8 percentile to get a call. Converting it would completely depend on your PI performance.
All the best!

Syllabus is totally different. It totally depends on you whether you want to go in service industry or in engineering. I advice you to think more, get information about both the things and then decide. You can post more of your doubts. Good luck.

Both have good job opportunities.
It totally depends upon your interest.
My advice for you is to go for commerce stream.

Hello Vignesh,
Many a times, there is slip between what we desire & get. Ideally speaking, it's better to be 12th pass than 10th pass. But if for some reason you have to take up job and can not pursue 12th, you can now do it as external candidate also.

Diploma in architecture could be pursued after 10th and after that, you can go for B.Arch.

You may look at colleges. However, I would suggest target a score of 6.5 on IELTS. In order to guide you further, could you highlight your 12th stream (commerce or science)?
