I want to learn algebra II, trig and calc over the summer but I have a terrible time learning by reading, so is there some youtuber that does tutorials or a program like code academy except for math? Thanks!
I'm like that as well, reading textbooks can be very boring indeed. There are tons of videos, look on learnerstv.com for example. You'll probably need a book to give you the topics but there is a lot of information online about school subjects.
Are good textbooks on these Mathematics courses rare in your location? The best instruction for these three are found in textbooks dedicated to them. YouTube videos from Khan Academy and some others (do a search on YouTube) are also very helpful. Practice exercises and example problems are necessary. Two other sources found on YouTube which are helpful are DrJamesTanton, and BullCleo1 channels.
