I want to do BSc in MIT or Oxbridge with zoology honours. What should I do to get into any of them?
The success to any application for being accepted at any prestigious university around the world requires lots of preparation, motivation and a passion to learn a subject and contribute the outcome of the learning for benefit of humanity.
Undergraduate studies
Specifically, about Oxbridge, Cambridge University, I would say requires a lot of preparation beforehand while applying. You should be aware that Oxbridge follows a tutorial system. Before making any application you should always ask yourself will you be comfortable with such type tutorial learning system.
Academics
Since the competition is tough or I would say extremely competitive, they set a high bar of expectation for non-UK candidates. Specifically, candidates from India should have 92% and above in PCM(physics, chemistry, mathematics) if applying to an undergraduate course related to technical studies. There are high academic conditions which you have to meet if you are specifically from commerce, life science, etc which could be around 90 % and above.
Oxbridge follows different deadline for undergraduate courses(further information can be found on the website, as it changes from year to year)
Funding
Undergraduate funding is different, it is better to contact the university and clarify your funding doubts. Loans are available for funding the studies
If you are from India, the major concern would be regarding funding, as the admission process is tough, funding is extremely intense.
May all of you be successful in whatever field of interest you choose to study, at the University of your choice.
My best wishes
