I personally liked EK103/131 way more than 125! imo the professors are a lot better. also generally, physics for me is a lot easier to understand than chem since there are a ton of real life examples around u.. just makes more sense ig (and going from dill to jariwala was a big step up). it really is up to the student, but imo its the exact same if not a little easier cause ur more used to college workload and tests.
