Surefire A, [@SheriffLlama], get together with as many students in your math class as possible. Have everyone do the homework together. Whenever someone has a divergent answer than the others, you all do the problem again until you are in agreement. I did that in my college algebra class, not only did we tear through the homework, the average grade in our class was an 80 something. We had multiple students break the record of the highest score that the teacher had ever had. I implemented it when I realized that this is the technique math super-brains use in order to check each-other for new proofs.
