Quadratics

Today has been pretty eventful (for me), I did 3 textbook exercises! They were all concerned in some way with the discriminant of a quadratic equation: calculating it, finding the nature of roots using it, or using it to solve problems. I found the last exercise very difficult, it's what I'm expecting the maths course difficulty to be at the moment, as I am now roughly halfway through. I have 2 more exercises before I finish the eighth topic in the higher course, and the next one is integration. That looks impossible because there are very scary symbols I have never seen before, however I am looking forward to trying it! I will do so once I have finished quadratics, and also revised polynomials. I will be revising one or two topics after I complete each new one from now on, then it will be less difficult when exam time comes (although that's not 'til January).
