Hello,

You are applying for TFW seat that mean tution fees waiver scheme.

TFW is scheme has been implemented by government for meritorious and economical backward students for admission in to universities and University's department.

So if you are applying for TFW category so you must have your income certificate.

If it gets cancelled then you treat as a ews category student but if you didn't any income certificate then you treated as a general category student.

All the best.
