If I know the foundations of certain topics in quant aren’t there for me - expect for watching videos and the mountains/ doing the end of topic quizzes, what else should I be doing? Should I be doing practise questions on those particular topics? I feel that I have a general foundation and then I’m unable to apply it. Would appreciate any advice! I feel like I’ve been stuck in a rut.
assuming you are proving you know the foundations thru mountain / quizzes, yes, additional practice like with the Manhattan 5-lb. is useful before moving on to another topic, if time allows.
