MCA

You need IELTS over all 6.5 band and each component 6 band to do any Masters in Canada. Take some coaching and rewrite the exam you will get the required marks. There will not be an MCA in Canada. You have many specialised Masters programme in Canada and there will not be an MCA. You can take any one field which is of your interest.

If you want to computer work or interested in programming then you can do MCA.

MAH MCA CET 2018 is a State Level Entrance Examination conducted by the Directorate of Technical Education (DTE), Maharashtra. The cut-off is still not revealed but will be nearly the same as the previous year's cut-off.

Every school follows a different slab for salary. The package also depends on your experience and not just the degree. The starting maybe approximately 30K.

It will cost around 2,21,000 for three years.
Good luck.

Both the courses are almost same. But in my point of view, MCA will be a better option after BCA.
Good luck.

The admission process starts in May and the last date to apply online is 30th June.

Well in my knowledge u definitely have a chance to get a seat in MCA with your Ts-ICET rank. https://www.shiksha.com/mba/exams/tsicet/counselling click the link for better guidance. all the best.
