JEE

Go for FIITJEE or Akash. You can also opt for Bansal or Resonance in Kota.

Just focus on JEE main because there is time.If you will do JEE course properly then you will get easy to prepare for 12 board exam.

Refer to NCERT books, keep your concepts cleared, try solving more and more questions and of course maintain contacts with your teachers.

Hello Shreyash,
Getting rank below is surely not a function of studying for 12th. Though the syllabus for JEE Mains as well as JEE Advanced is that of CBSE syllabus for 12th, the way questioned are asked is totally different. You must know the concepts and should be able to apply these principals logically in solving questions. After all someone this year has scored 100%, so it's definitely possible.

Hello Aman!
No. JEE is an all India examination which would provide you an opportunity to study engineering in the prestigious Institutes like NITs and IITs.
But it is not compulsory.
You may also go for other universities like BITS-Pilani, VIT, etc. by clearing the respective exams or a better college with your board exam marks.
All the best!

Dear,
I think dropping a year is not a good idea until you are confident enough to achieve your target. And whenever ensuring is under a question mark, you should keep strong backup circuit ready and the only important task is to make your sincere efforts double for pursuing both i.e. preparation for the entrance exam as well as study for ongoing B.Sc. course. Difficult but not impossible.
Best wishes.

You can take the SAT either in 11th or in 12th.

Hi Pratiksha,
You have to take entrance exam i.e JEE Mains for this purpose.

Hi there,
I have the same resolutions and I'll also give my SAT in 2019. Here's what you should do; if you are a resident of Delhi, you are lucky. Just join Vidyamandir Classes or FIITJEE-South Delhi and do not attend school. Simultaneously, work on your vocabulary and get enrolled in the Princeton review at New Delhi. Do like the answer if you found it helpful.
