Is there any way to post without giving them a single star. coz they dont even deserve a single star. I am regretting why I suggested my sister this college.
1. Teachers are inexperienced (They hire low payed teachers just for cost cutting).
2. No support from management at all.
3. They just know how to make money.
4. Never refund caution money
5. Its a BIG NO NO From me for this college
** REMEMBER I DON'T WANT TO GIVE THEM EVEN A SINGLE STAR.
