Thanks for the question

Every chapter comes in some or other types  hence you cannot leave anything.

Dimensions are important.

Vectors- you can always expect derivations.

Pulley experiments are always asked.

Friction is also not to be skipped

Electromagnetism amd optics are to be read and practised. Very important chapters

Static and current electricity numericals.

Some theoritical questions are also asked. Value of G , SI UNITS.

Good luck
