Hey!

If you're talking about taking coaching during your graduation, I will suggest you to take coaching on graduation base. This will help you in clearing further entrance examinations for postgraduation.

Also, if you wish to change your field of study in postgraduation, then you can take coaching for entrances in that field.

If you wish to seek government jobs after graduation, then do look for coachings for Bank PO exams, SSC-CGL, UPSC etc.

Hppe it helps!
