Canada

Hi Pushkar, to get into the top universities more than 75% is preferred. A first class grade is recommended on the whole. Also, minimum requirements may vary from university to university and vary with programs as well so you must check the desired university website for details.
Hope this helped. Feel free to revert for clarification if any.

Yes , check out http://www.edwiseinternational.com/study-in-canada/application-process-canada-universities.asp
give it a try

NewZealand is the best option . After one year Level 7 program you will get one year work visa. Once you get job you will be given two year work visa.Once you get work permit you are eligible for PR

as you are looking for cost you need not take up studies in Universities . you can do it colleges which will be less than universities

the intake is August and February. At least one month advance you have to apply for visa

Dear Jhanavi, yes you may apply for courses in Canada with or without Maths. It depends on your academic scores & also on the subjects you have studied in India. You must give IELTS too for the application.

there are no specified exams but you can give sat ans sat subject test with biology and portion will be the same what u have studied in 11 and 12th best of luck

Dear Vipul,
As mentioned by Anjali both countries are sound as far as post study employment goes, however with the new Visa guidelines coming into force from 1st July Australia would be a better choice as chances of PR are clear and poststudy work visa for graduates and above is 2 years. Climate wise also you may prefer Australia.

You can consider Biological Science, Biomedical Science etc.

Hi, please check ICM- Pathway to University of Manitoba as you can take Math there since you havent scored well in Maths here.
