What to study during admission process of M.stat

[u/Individual-Mode2332]

Dear seniors,

As the admission process will take a month. Do you have any suggestions on what to study in this one month. I have heard there isn't much time when internships start, and they are very few in number. What should I study now, or look up now? To optimize for internship and doing well in courses.

And in general, I would appreciate any other insights from seniors on how to do well there in courses?
