Class 11

Dear Deepak,
We had to finalize the academic calendar for your batch as well as the commencement date. They have now been resolved. You will be getting your admission letter within this week. The course commencement date is June 19, 2017. Call the office for status update.

It depends on university criteria, rules, norms and regulations.
All the best.

Hi Ritik,
You did not mention if you are a PCB student or PCM. Also, you have to be more specific with your interests so that I can guide you accordingly. Here are some common optional subjects but the list will vary from school to school.
Biotechnology, geography, economics, business, agriculture, computer science/informatics practices, graphic design and mass media studies and much more.
Take a psychometric test to know your aptitude and figure out what you like.

You have only 20 days left. So better revise the chapters which have more weightage of marks. Mechanics is the most important part. So try to complete this part. Most questions are asked from that part only and practice numerical problems also and there is no need to revise the derivation which is a big relief.

You should take science as the field requires physics, chemistry and maths with a minimum of 55 percent marks and also English. Feel free to ask if you have any other queries.

No, opting for computer science in class XI don't have any relation with mechanical engineering. To pursue B.Tech in ME, you need to score good marks in physics, mathematics and chemistry.
Best of luck.
