hiii piyush.....
its very sad to listen that your marks are v low and increased marks are also not up to the mark....but now you cant do any thing....you can only give re evulation form only once....the cbse re check the copy v well ...i hope you had got your copy and realise your mistakes....
and yes you will get another marksheet ...and your marks will not get decreased not matter how many time you apply for re evulation....now the only thing you can do is give re exam....
hope u like the ans....dont forget to upvote
