Hello Pratap,
No, it's not difficult to score 150 marks. Study is the most important key to achieve your goals.
Study well and don't take pressure. Keep calm and enjoy your work.
All the best.

Improve your basics, do more and more numerical, time management, enough sleep, and last be positive towards your goal. Don't be a day dreamer.

Yes, you can definitely get some top private colleges like BITS (if you appear for BITSAT), LNMIT-Jaipur, PSG College-Coimbatore, MIT-Pune, BIT-Mesra and some of the government colleges too.

It depends on the area where you live. Prefer better faculty first. If you're an average student, interact with seniors. Keep in mind the pros and cons of joining each institute and then take your decision. Even then Allen test material is good. If private tutors are better, join them. Good here means someone who is tried and tested on the JEE level, not on the school level. Approach a teacher who can make you understand things is better than one who gives tough questions and is unable to make you understand them if both the teachers are of the same level.

Hello Sir,

Not necessary. You can apply through passport details.
