You are perhaps going for one of the most difficult streams of M.Sc, which is, of course, Maths. Few of my friends are studying there and as they have mentioned, by the time you reach your third year, one of the subjects in Maths would have a good number of theorems.
The next thing you would have is coordinate geometry as a part of your Maths 1. This would come in handy while solving double/triple integrations.
However, this is still the base of things. It gets complicated ahead- although, not sure if that would be in the third year essentially. Perhaps for better clarity, you should try and reach out to someone who is actually doing his/her M.Sc from BITS Pilani
My friends mentioned that students who are carrying along two degrees at the same time have CS as their ultimate aim. There were a few friends of mine who with a double degree, either ended up slogging into semesters, achieved CS with hardly any effort, and eventually, some of them had to choose chemical/civil out of sheer compulsion.
If you're trying to decide between pursuing a Master of Science in Mathematics at BITS Hyderabad and a Computer Science Engineering degree at Vasavi College of Engineering, here's some information that may help you make an informed decision.
If finances are not a major concern, it may be a good idea to choose BITS Hyderabad's MSc Mathematics program over Vasavi's CSE program. The reason for this is that in the second year of the MSc Mathematics program, you will be allocated a BE degree. If you have a good CGPA in your first year of the MSc program, you may be allocated a good B.E. degree, such as in Computer Science Engineering (CSE) or any circuit branch.
This is significant because a B.E. degree from BITS Hyderabad is highly regarded and could provide a good return on investment in terms of career opportunities and earning potential. Additionally, BITS Hyderabad has a reputation for providing quality education and exposure to industry-relevant skills and knowledge.
It's important to note that while a good CGPA can increase your chances of getting a desirable B.E. degree at BITS Hyderabad, there is no guarantee. Additionally, pursuing an MSc in Mathematics and a subsequent B.E. degree may require more effort and time commitment than pursuing only a CSE degree at Vasavi College of Engineering.
Ultimately, the decision between BITS Hyderabad's MSc Mathematics program and Vasavi's CSE program depends on your personal preferences, career goals, and financial situation. It's recommended that you research and compare the programs, their admission requirements, course curriculum, faculty, and placement records before making a decision.
