Depend on your interest

Yes you can. IMU CET exam is conducted in month of May or June every year. Exam fee for general category is Rs.1000 & for OBS it is Rs. 800.

If you want to do B.Com (hons.), then it's not compulsory to take math in 12th.

No Maths is not required for simple B.Com. Do apply in as many courses you are interested in Delhi university so that you do not miss a chance to get admission. All the Best.

Yes GMAT is required for you. You will only be eligible with a GMAT score. Aim for a score of 680-720.

Discard RS agrawal/RD Sharma.They are completely extrapolation of the concepts and various chapters.
Use NCERT and TOGETHER WITH for reference.
Together With Mathematics contains last 10yrs questions separated Chapter wise.Do that along with NCERT.
Concentrate on book 2(NCERT) properly as the second book carries more marks but don't forget or ignore the 1st one.
The paper can be tough next year also.
CBSE board exams are unpredictable.
Give your best and be prepared for every kind of paper.
Good luck mate!

Change in MBA without giving any exam is not clear. You can give the exam like XAT and MAT because admission through CAT is a bit tough with this percentage. But anyways give it a try. All the Best!

Give entrance exam like CAT, XAT, MAT, CMAT, CET. Join good coaching classes to prepare and work hard to give mock exams. Read newspaper daily.
Good luck.

You can choose 'Together with Biology' . All chapters are written point wise and its very easy to read. try it . you will not regret. NCERT will be in your fingertips if you read that book
