Dear Aspirant,
Congratulations for cracking the Cucet examination.
You completed your batchelor of science in chemistry.
Now you wants to persue your master degree.
But you are confused between two universities called "Tamilnadu central University" and "Kerala central University".
According to infrastructure, faculties, hostel facilities,study environment, library, laboratory etc both are same.
You can go for any of one University between them.
Because master degree is Research oriented.
IT is completely depends on you.
Best of luck.
