Dear Aspirant,

NO. Slip is not the certificate. It is just proof that you've applied for the certificate. It does not guarantee that you'll get the certificate. I suggest you should better get the certificate before the document registration starts or you'll not be allowed to take admission in the college.

Hope this helps.

NOTE: If you don't get the certificate in due time, then go with the slip and try to talk to the administration and explain them your condition. Maybe they'll allow you admission.

Thank You and All the best.
