LSE MSB or Actuarial Science?

I'm applying to LSE, but I'm unsure which course to choose. I want to become an actuary in the future, but I've read that an actuarial science degree might be less competitive compared to a STEM-related course when it comes to job prospects. Would it be a better idea to apply for the mathematics, statistics, and business course at LSE rather than actuarial science?

I would recommend doing Physics with Maths at Imperial, Oxford, Durham, MORSE at Warwick or UCL, or Natural Sciences (Physics and Maths) at Cambridge, rather than either MSB or Actuarial Maths at LSE, as you have a better grounding. Engineering Science at Oxford would also be useful, as you will need to understand technical aspects not just statistical / econometrics.
LSE is an Economics focused school, and is not renowned as a Maths school. Also, be careful with LSE as 73% of students are International and LSE 'games' the various rankings because of it.

MSB for sure is better as it is more competitive and keeps everything open

Got it, thanks!

Yeah I had a friend who did MSB at LSE and became an actuary so do not worry, it just helps keep everything open thats why I would recommend.

All you require is A-Level Maths and two from Economics, Further Maths, Physics, Chemistry, History, a Language or Geography.
Actuarial science is not offered by that many top universities, so you might as well focus on a Maths and Statistics degree.
