Hi

What's your father's correct name? Rajesh or Rajeshwar?

If Rajesh is the correct name then simply get a new category certificate made with correct name of your father.

If,

Your father's name on your 10th& 12th certificate is wrong and correct name is as written on the category certificate then you need to contact the board from which you have passed 10th & 12th for name correction but that's a complex process and again not all the boards offers this facility.

So,

What you can do is simply get an affidavit done mentioning that both the names belong to the one & the same person i. e your father's and carry it along with you during document verification.

Now that,

limited time is left for neet 2022 , so you should be focusing on your preparation,

***** practising chapterwise questions

***** then revising the chapters,

***** solve at least previous 10 year neet question papers as concept behind the question often gets repeated in the examination so it will be of great help in your preparation  ,

***** go through neet mock test papers as it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination.
