One of my cousins is part of the institute and has varied opinions. Primarily, it depends on the faculty of the institute. Other than that, here are things he says are essential to note,

1. The papers usually in ME can be slightly difficult to ace. However, if you are in your 1st year, you should completely avoid copying from your peers.
2. Try maintaining a good attendance score since it will help acquire at least 35 out of 50.
3. EC department can go on to creating trouble. Although, it depends completely on the faculty.
4. For other departments, you should choose to attempt every question instead of skipping them since it might help you achieve marks over 40, with the addition of your attendance.
5. You should always maintain a cool temperament with the faculty.

Other than that, always be vigilant. Hope this helps answer your query, wish you all the best!
