 There's a classical mechanics lecture on YouTube by Harvard professor where he tells his students that they'll have to know around 104 minutes for the class. He said they have two options, either memorize them all or memorize four of them and learn how to drive the others. Cool. I would probably, if that's the classical mechanics course, maybe if you would, see here's the thing with courses that require memorization, right? If they're good courses, if they're good courses, they're not just handing you stuff and saying memorize this, they're giving you questions where you have to work with what it is that you need to memorize and if you do all those questions it just becomes part of your knowledge base, right? So you don't have to memorize it, it's just part of your knowledge base, right? It's like learning a language, right? So that's the way a course should be outlined. So if this classical mechanics course requires you to memorize 100 formulas, I'm guessing at least 50 of those formulas, if you take this course and you do all the problems, are formulas that you're going to be using during your problem solving, right? On a regular basis, right? And another 25% are things that appear fairly commonly and then 25% is probably something that, you know, you had one problem that had it, right? So if you just do the problems in a course like that, you should easily pass. If you want to ace a course like that, difficult. You have to memorize all 100 formulas. Like, for example, the example I gave you with me at university, I had no desire to ace that course, right? I've never had a desire to ace any course that requires just full-blown memorization, okay? But if I did, I would have spent the time to learn all those. Maybe I would like it, right? Maybe it's something that I want to do, right? I want to learn all the chemical formulas for these things, right? Maybe I get a kick out of that, right? It's a collecting comic books. I get a kick out of collecting comic books. Maybe someone gets a kick out of memorizing formulas, right? Chemical formulas. So they would do well on that course, right? Every course is not for everyone. But if you're, you put a certain amount of effort to every course that you need to take, the odds are you should be able to pass them, right? You should be able to pass them to move on to the courses that you really want to be in.
