Madurai

Hi Kavi. You can go through the college rankings and the Alumni of the college in Madurai. I will advice you to select that college who's average package is total of your fees. Means best ROI. You should always see the ROI before you select a college. One of that college is Sri Balaji Society Pune. Who is been known for its corporate training also the ROI is best among Pvt college.

Your may pursue BSc in Viscom from Madurai Kamaraj University.

Well dat sounds very unfeasible. Advise you to stick with the college you are in to avoid any job related issues.

One can appear from any city for the competitive exam,provided that city has an exam centre. Since these are All India based central recruitment tests ,the Banks follow laid down norms for Placement post selection & completion of training .There are chances of getting a posting of choice but there is no certainty in it .

Don't trust any rankings. TSM is a very average college. what other options do you have in Bangalore?

Madurai Kamraj University is recognised by UGC.
