Australia

Hello Sai,
You have to invest in some hours every day and research on universities offering integrated Ph.D. Victoria University and Edith Cowan University are few of them. Contact the universities for availability in biotechnology department Ph.D. Don't keep yourself limited to only Brisbane as you might not find any options there.

You should score at least 60% in your graduation.

Could you be more specific about what exactly do you mean by branches?

No, GRE is not required for MS in UK or Australia only IELTS is required, if you are looking at post study work and PR then Australia is a better choice, however enroll for a 2 year course as only then you will be eligible for PR. Cost wise UK is lesser as it is only a 1 year course but no PSW or PR.

Dear Avikash,
You must gain work experience before you apply for an MBA program. Since your graduation percentage is quite low you must focus on obtaining high grades in your PGDBA and also gaining work experience is absolutely necessary.
