B.Sc

Hello Ruchita
Yes, you can get direct admission in MCA.

Hi,
If you're having a BSc degree in mathematics, only then will you get admission into M.Sc Mathematics as maths is the main subject and is required in B.Sc final year, if a candidate wants to do M.Sc in the same.
In addition, you must first check with the cutoff percentage as yours is a bit low.

Hi Rutuja,
I believe that for admissions into M.Sc. Microbiology, you need to have a B.Sc. Degree in microbiology or a plain B.Sc. Biology. I don't think B.Sc. Hotel management fulfills the eligibility criteria. You must still confirm with what university you want admissions into as it may vary.

Hello Ansari
Top 10 colleges for B.Sc are:
Loyola College, Chennai
Christ University, Bangalore
Miranda House, Delhi
Madras Christian College, Chennai
Hindu College, Delhi
Sri Venkateswara College, Delhi
Hansraj College, Delhi
Stella Maris College, Chennai
Ramjas College, Delhi
Gargi College, Delhi.

The fee for the BSc in catering technology and culinary arts is roughly 4-5 lakh in any college across India. Although this is just the tuition fees, you will need extra expense for hostel and food.

MBA in SCM is a good choice although do check the career prospective and I hope you have a good plan because they would ask for that. Also, check Shiksha's college predictor for colleges in Kerala.
