Class 11

Hi,
You can opt for IB in class 11th as per your interest. But, it isn't compulsory.
In my opinion, pursuing BBA through distance mode isn't a wise choice. There are good colleges in the country that offer BBA through regular mode with lucrative packages and you should aim for that after your class 12th.
Some of the colleges are: -
Symbiosis International University
Delhi University
Christ University
Mumbai University
SPJMIR Mumbai
IIM Indore - Integrated BBA and MBA
You can start preparing for the entrance exams.

Hi,
I guess you are left with only one attempt of JEE Mains i.e. just after class 12th. You will have to get a year gap certificate for admission in any college.
All the best.

Hi,
It depends on what you want to study, you have options like BCA+MCA, CA, computer science, B.Com+M.Com or B.Com+MBA and BBA+MBA.

Score well in class 12th (PCME) board exams and JEE Mains.

Hello Chitrangi,
Presently, you are in 11th and is desirous of appearing in different exams. But which exams? Towards Engineering or medicine? What subjects you have chosen at present? For medical it's only NEET. For engineering, it could be JEE or CET of your state and of some private university offering degree in engineering. Just read newspapers and you will come to know.

From science, you could only switch to arts. There is no option of shifting to commerce.

Your 11th marksheet isn't important. However, you can ask your school principal to give you a certificate that says that you have passed 11th standard.

HI Tanmay Kapil,
Yes, absolutely. Complete your 11th and 12th with high academic percentile and get involved in high end extracurricular activities too. If you want to study in USA take the SAT or ACT during your 11th or 12th. You must also take the TOEFL or IELTS. Decide where to study and what to study first, accordingly you must check the requirements and prepare.

No. You have to pass class 12 too.
