Teachers demanding sweets for marks

In our college, teachers refuse to give marks for practical subjects until and unless sweets, etc. are given to them.  Is this correct?

When the students study with their own hard work and gain knowledge from the teachers, then on their success or at the end of the academic year, out of their own happiness or as a form of thankfulness to the teachers, if they give a party to the teachers or give them some gifts, then as per the Shariah, there is no problem in it.

This does not come under bribe.  On the other hand, if the teachers demand a party or gifts, to pass the students, then this demand is not correct, but comes under bribe and taking bribe is expressly forbidden.  As given in Radd Ul Muhtaar, Kitabul Qadhaa

And Allah knows best.
