Just a little mistake i did in filling the examination form..

I have passed PCC nd I am serving my last six months of articleship..
 

so i should have selected CAT V as my eligibility but I selected CAT I which is that I have passed my Intermediate exams. I noe its a silly mistake, but ho jati hai kabhi kabhi.

However I have filled the roll nos nd examination passed correctly, now tell me wat should i do.

should i correct it with a pen??
 

vaise toh our principal signs in the required category which is in the last two pages, but still I am a  lil scared
