No, in MMU, at a time, you can do only one full time course.

B.Sc. Food technology is a good course and out of these two, Ernakulam a more better option than Kottayam as Ernakulam provides more exposure and there is another option of TKM (Thangalkunju musaliar college) kollam is also a better option and Ernakulam is more of a city life and Kottayam you have to travel, so Ernakulam would be a better option.

Fees is Rs 1.06 lakh.You can consider following:
