A name mismatch between the RRB Clerk application form and your identity documents can create a problem during verification at the prelims exam centre. Your admit card, ID proof and application details must match exactly for the staff to allow entry. Even adding or removing a surname can be considered a mismatch.
However, in many cases candidates are allowed to appear if the difference is very minor and they can prove their identity with valid documents. Since you wrote “Ashish Mehta” in the form and all your documents show only “Ashish,” the exam authorities may ask for clarification during document verification.
