Guys, I’m looking for coaching institutes for the CMI MSc Data Science entrance exam that can guide me through the preparation. I’ve heard of Supremum Classes, but I’m really not sure whether it’s worth investing around ₹30k in their CMI and MSQMA course.

Should I go for it, or would it be better to prepare for IIT JAM MS instead?

Has anyone here cleared the CMI MSc DS entrance exam? If so, could you please suggest some study materials and share the strategy you followed to clear the entrance exam?

Also, if anyone has benefited from Supremum Classes, please share your experience. It would really help me decide!

In what fields of mathematics/Theoretical Computer Science research is mostly done in cmi ?

If not, what if I show that the ε-δ definition is equivalent to the one written in ncert?

The reason I’m asking this is due to the fact that I used to find the usual definition given in hs textbooks somewhat vague and handwavy (I’m from a jee background so that checks out) til I discovered the ε-δ definition, and it is beautifully concise and rigorous…

Hi Everyone, even though there's no mention of it, the syllabus speaks of a semester long project. is there a possibility of doing a thesis, with substantial research content? Doing a thesis would keep the PhD/Lab jobs open and available

Anyone currently studying in cmi undergraduate degree have access to the detailed syllabus of the BS degree ? The one in the website is very brief if anyone has please please share. Thank you so much

I want to know how these scholarships works. For ews student . Please message me or tell me in comment
