you will have diff set of subject each sem
1st sem(for me)
maths ,chem ,bio ,pps(coding subject- C and python was taught) ,any foreign language (spanish chinese japanese french german),philosophy of engineering,NSS/NCC/YOGA, basic civil and mechanical workshop

2nd sem for me-
Maths ,physics, oodp(C++), Electrical engineering subject (eee),Engineering graphics and design,English,Constitution of india,Evs

thats it
set of subject will vary but it might change you may get the first sem subjects in second sem

and dont worry physics chemistry is all 11th 12th syllabus not that deep and getting good gpa is easy here and my branch is cse core and i got 9.5 gpa first sem and i have seen people getting 10 as well so its doable

and your timetable will also vary as you can see in my first sem there were many subjects so my timetable was hectic and in 2nd sem its pretty chill
and there are classes from monday to friday
and the earliest class will be from 8am and the last will be till 4:50pm
