Hello aspirant,
I am here for helping you....
As per your doubt I am clarifying you that this semester it happened with many of the students..
now I am guiding you that what you should do in this situation...
As you already know  the cost of revaluation process is very high and as per the latest rule of AKTU  they will refund you only 3,000 rupees out of 5,000 if your marks increase..
And in the previous year you used to get refund of your 5000 rupees if even a single mark is increased.
And your money used to refund twice of 5000 if you your marks increased more than 20% .
So, you can file RTI ( Right To Information) here you will have to write an application with the attachment of your college ID card and admit card then you will have to speed post it to the public Information officer of AKTU.
As per the act of RTI 2005 they will have to respond within 30 days.
using it you can seek your answer books of subject in which you got less marks.
After having answer books you can show it to your college teacher and then they can easily guide you that how much marks should be increased in your answer notebook .
If there any chance to increase marks, then you can case on aktu in district consumer forum for leading to the  damage of future of a student.
if you don't want to case on the university then after having notebook you can apply for the revaluation process, where you can ensure yourself that marks are going to increase after having answer notebook in your hand.
I hope it will be beneficial for you....

Dear aspirant,

I always suggest to students out there and me being a student too i have leart in the hard way. There's a huge misconception that after revaluation, our marks will magically increase. I had paid for revaluation and a friend of mine did the same. I got an increase of 5 marks in maths and the remaining increased by a few marks though it didn't help my grades much but it did calm me down a bit. Meanwhile my friend got downgraded from 21 to 10 marks in BEE. similarly he got downgrade in maths from 42 to 36. This is why i strongly am against revaluating unless its a situation where one is failing and needs 2 marks to clear it.

My suggestion to you would be don't stress about it much as long as your semister is clear do better next semester.

ALL THE BEST
