This is a review for both Physics A and Physics B together.
If you enjoyed 1A Physics, this is the course for you!
Doing double physics and something else (say chemistry) is perfectly manageable too, but you may find yourself at a disadvantage compared to the people doing maths in some topics.
The supervisors are all helpful and supportive, and are willing to spend lots of time if you want it. The experiments are far more independent than 1A which I found good, and you don’t have to do write-ups each week like the chemists. Also if you have the choice I’d say try to get on the Friday/Monday afternoons slot rather than an all day eight hour slog on a Tuesday or Thursday.
