#EngineerChallenge Day 008 

It's #Monday and we're going through the motions again. I don't think I take too well to problem sets that ask questions that are open-ended when the topic is supposed to be quantitative and have a definitive answer. I get that the #pedagogy intention is to have the lessons be transferable to a wider context than mere test-taking but it does not help at all when it's for a board exam (test-taking in its epitome). The bigger underlying issue here is that recent #textbooks do not provide good answer keys in the back anymore. It's either odd or even numbers that are given (what about those who self-study and want more practice?!) Sometimes, they are not even complete and only giving answers for specific sub-items a/b/c/etc. It's like the textbooks' pRiMaRy gOaL is targeting professors for pRoFiT and *not* quality #education.

Maybe I should look elsewhere? Or should I stick with it and skip the awkward open-ended questions? I would've liked trying my hand at the open-ended questions if I had the time but it just does not make much sense in a self-studying context. These types of questions are usually reserved for discussion groups.

What if open-source textbooks would be good? And more common? Similar to what OpenStax is doing, with a primary goal of quality education (and no extra answer key locked behind a paywall! [0]).There's already #git, #LaTeX, and #typst for that.

[0]: Usually as part of a solutions manual... I don't care much about the solutions manual, I just need the answer key to check my work in a self-study context!
