I found the class very preparing, and they taught you many strategies. One word of advice is to get going on the homework as soon as possible and time yourself each and every time. I found my instructor (Ben Smith) very helpful, although we did waste a lot of time going over problems from homework. In the future, it appears they will add videos to the grading section to help the flow, a big improvement in my opinion. I also found most of the strategies very useful, but sometimes too exaggerated, but the practice can help you find what works for you and what doesn't. Good course overall.
