CBSE

You can try to get admission in VIT and SRM.

Yes, you do have a choice. The improvement exam form will release in July.
This is totally an online process so there is not any type of difficulty.
Your exam can be scheduled for next year with the board exams, without any practicals.

70% for PCMB in CBSE is not that bad. For you the career options are countless. You might go opt the following:
1. Engineering (Stream can be chosen according to your interest)
2. Medical Field (MBBS or BMS)
3. B.Sc. (Again stream to be chosen according to your interest)
4. Law (if interested)
Other than that if you want to choose any you can.
In the end you have to decide what your interest lies in.

Please mention your interests.
Whatever maybe the field in demand, choose what you will enjoy to learn and practice.

If you are dedicated of course you can.
Some of my friends from CBSE managed upto 9.4 and 9.6 scores.
All the best.

Hi Mohan,
Please check with your school and education board, they will notify about the exams, forms and dates. Improvement exam can be taken even if you passed and to improve your scores.

Dear, it is not possible for you to get admission anywhere if you have not cleared all the subjects in 12th standard.
I would suggest you to challenge the evaluation of your failed subject, If you are confident enough you should do as suggested .
Just go to any of the board office of the respective board and file your grievance .
I hope you pass the subject after challenge evaluation, and then you would be able to take admissions .
