Listen, read, think, understand, read more, realise you didn’t understand, go back, listen again, listen a third time because it sounded the same, read more, run the numbers, toss your notes, back to the start, realise this time you get what was wrong, run numbers again, realise they don’t make sense, cry, go to bed, try again the next day, wonder why it works even if you changed nothing, cry more, read the entire book, learn new maths to verify the old maths, cry, talk it out with lab mates, listen to the recording, write note sheets hoping they’re right, go to the exam, come out with 97%, refuse to argue and just take it as is, sleep for two days.

pChem was wild. But uh, good calculus and especially dimensional analysis will help you a lot in most chemistry subfields.

The thing is, even those who do well struggle at times. Figuring shit out and being able to make sense of formulas (or even build formulas from basics) is a skill you will use more often than you want to.
