Hi friends, I am a new member here. I have a bit of a dilemma here, so I thought it would be best to ask your advice on this. Thanks in advance for all your inputs. So, the problem is I have to pick one specialisation area in my UG, either Theoretical Physics or Theoretical CS. I am really confused between the two. I am a math major and I can confidently say that I am fairly good at it. I have taken courses in Abstract Algebra, Analysis, Topology, Probability & ODE. The problem is, I am neither interested in CS nor Physics. I am planning to take graduate level Math & Stat courses, so, I would like to know which is harder - Physics or Theoretical CS? Although I don't like Physics to the point that I want to do PhD in it, I do like Applied Math. Some say that Theoretical CS is Applied Math, but, all I see is recreational math problems that I encountered in Olympiad. Moreover, I would chooce Theoretical CS ONLY IF it is significantly easier than Physics, otherwise I would go with Physics - if they both require same level of work. P.S: Don't get pissed off with my question, I am well aware that these things vary, but, please give me a general advice on which is a GPA-killer!
