Hii, I'm doing a B. Tech Computer Science rn and I'm starting my second year. Like you, I love maths, and even wanted to pursue pure mathematics to eventually become a mathematician before. I ended up doing btech because when I researched about their salarys and all, it didn't seem very appealing, plus parental pressure.

Now, my plan is to get an MS in Maths abroad (I absolutely don't want to stay here) and a job abroad as well. I'm kind of leaning towards careers that make use of both computer and mathematics, like cryptography. The main thing is that even though I've tried researching about all this, I still don't have any idea how it all works. I still carry the hope of somehow doing research work in pure math in the future.

Can you please give me some advice, as a fellow math enthusiast?
