Hello Mani Billa,

Improvement exam is only to improve your grade but if you fail it will not affect your report card means whatever you have scored earlier will be same, no changes. As of my knowledge there is no such kind of compartment exam for improvement . 86% must be enough but if you want improvement then you can apply for it.Hence even if you fail in the improvement exam there won't be any problem.Hope you have understood what I meant and your doubt us cleared.Thank You.
