Hi aspirant

hope you are doing absolutely fine

You will be giving your exam in the month of August, so technically you will be a student of final year and not graduate yet as the results will be announced later. So it is good for you to go with the code 5 as -

code 5 is for a candidate who has passed 12th standard or equivalent examination and is now pursuing a 3 year degree course  from a recognized university. For more you can this link -
