Hey Baliram !
Yes, you can apply for more than one subjects to appear for the improvement exam, the major subjects of Maths, Physics, Chemistry and Biology are well included but you must keep in mind some of the basic rules.
1. You should have passed in the subject at the least.
2. The Improvement exam can be held only for the succeeding year of passout.
3. You can appear for the improvement exam only once.

Hope this helps.
