Hi, I am a working mechanical engineer (Bachelor), and am trying to learn math (again). My grades from virtually every math class I've taken are great, but I now know that's the case because my school was rubbish. The last two months I've done a bit of math daily. I'm currently going through the linear algebra course using the video lectures, notes and book from mit ocw. The course is far more demanding than the one I took several years ago. My question is, how long do you guys spend going through such a course? Do you re-read the book several times to make all the theory stick? Up till now, I've read all the material, done all the problems that have solutions and done the first Quiz. I scored about 60% so there's still work to be done... Before I give another Quiz a chance, I am re-reading some theory and might do a problem or two. Is this a good way to go about it, or do you guys have some better suggestions? Thanks.
