Dear Aspirant, 

After the declaration of answers and scores, the authority will schedule a period of time for applying to revaluate their papers in official website. 

The desired students will have to pat the money prescribed which may be around ₹750 for a paper. 

And soon the results for this revolution will be out. The process will be same and have an eye on official website to not miss this out. 

Hope this helps. 

Good luck.
