My dear Rahul ji, You’re asking a very  important CUET UG application doubt — good that you’re confirming now. Our cuetnow.com team is answering clearly point-by-point.

Question 1)  Should marks of only 5 subjects be filled in Class 10 section?

Answer: No.
In the CUET UG application, you are supposed to enter marks of all subjects mentioned in your Class 10 marksheet, not just best 5.
NTA asks for actual board marks as per marksheet, even if your board later calculates “best of 5” percentage separately.

So filling all 6 subjects is correct if your marksheet contains 6 subjects.

Question 2) If only 5 were required, can the form be edited after fee payment?

Answer: Even after fee payment, NTA opens an “Application Correction Window” for CUET UG.
During that period, you can edit academic details like marks, subjects, etc.

But in your case — no correction is needed, because you already did the right thing.

Question 3) Will entering 6 subjects lower overall percentage and affect admission chances?

Answer: No impact at all on CUET admission.

Because:

• CUET admission is based on CUET exam scores, not Class 10 percentage.

• Class 10 marks are used only for basic eligibility verification, not for merit ranking.

• Universities never calculate admission merit from Class 10 “best 5” or “best 6”.

So even if your best-5 percentage is higher, it does not matter for CUET UG admission.

Final Answer in Simple Words

• Filling all 6 subjects = Correct

• No need to edit form

• It will not reduce admission chances

• CUET score is what decides admission
