CBSE 12th

Hi Namit
Follow these steps and you will score well hopefully:
1. Utilize your summer vacation time to give a thorough reading to every chapter of each subject of ncert and if you can make notes simultaneously, it would help you big time in boards.
2. Identify your learning style as ppl learn by listening, writing or visuals so whichever way u learn the best, adopt it.
3. Subjects like maths n physics require lot of practice so assign stipulated time for these two everyday.
4. If you are taking any coaching, clarify your doubts everyday so that concept building is strong enough.
5. Practice as many mock tests as possible to improve your speed and understanding of questions.
6. Eat healthy, exercise a bit or walk and stay stress free. In case off any problem, consult a counselor as we are trained to help you through therapies, techniques etc.

Hello abbas,
FMS doesn't give weightage to your past academic scores as of now. Thus, yes you are eligible for admission to FMS. For further eligibility criteria you can refer www.fms.edu.
Talking about the percentile required.
The cutoff for admission to MBA programme 2016 is composite score of 59.430 for general category candidates. The Composite Score has been computed by giving weightage of 40%, 30%, and 30% to the scores of VRC, DI/LR, and QA Sections respectively as provided by the CAT Centre for the CAT 2015 Examination for candidates who registered with FMS. For example: Composite Score = ?(Score in Section * Weightage)/Max Marks for the Section
