My name as per GRE standard is mentioned as SWAROOPKUMAR PAL. While rescheduling the exam there is one filed required as 1st faour letters of the last name. Now as my last name has 3 alphabets. What should I probably enter in to that field. I have tried "PAL" "PAL " " PAL". These result in profile mismatch. Please pour in some views.

Regards,
Swaroop
