Hello,

as you mentioned it is practical exam so there won't be any question like MCQ or subjective. marks will be given on your practical performance and viva. respective subject faculties may take viva through pen and paper.

to get accurate details, it is better to ask to your subject teacher. they can tell clearly how marks will be evaluated and what will be the process.

There is no clear cut rules. different college take exam in different way so it is decided by the faculty how students will be assigned with practical topic and perform them. on what points students will be evaluated. it is all in teacher's way.

Hope it helps!
