Hello

About CSAB SAF Payment:

Since you already paid SAF in JoSAA Round 6, you don't need to pay SAF again in CSAB Special Rounds.

You can directly use that payment to participate in CSAB.

About Withdrawing to Avoid Paying PAF:

Yes, withdrawing before paying PAF is smart if you don’t want to join GKCiet and want to avoid non-refundable PAF.

This will allow you to participate in CSAB without losing PAF money.

Tezpur University Admission through NE Quota:

Your rank: CRL: 460k

OBC-NCL Rank: 160k

With these ranks, it is very difficult to get CSE or ECE at Tezpur University, even under the North East (NE) quota.

You might have a slight chance for Food Engineering and Technology or lower-demand branches (like Mechanical or Energy) under NE + OBC quota . if vacant seats remain in CSAB.
