The entrance exam of law is not difficult as compared to JEE or other entrance exam.
If you can give 2 hours from your daily routine and read the newspaper for daily update that will help you to crack the exam, but you have to manage the time very smartly.
So, do well in your exam.
All the best.

Syllabus of both is almost same. So, when you study for one, you automatically prepare for the other. If you are from CBSE, then syllabus is identical. Don't worry. Be calm and prepare.

Dear,
Yes, you have to appear for JEE because through that only, you would get good colleges for B.Tech mechanical engineering and get the knowledge and right skills for the same.
In M.Tech level, you have to choose specialisation like Mechatronics, robotics or you can think of aerospace too.
All the best.
