Other resources

Factoring: I found this wonderful resource that you can use to practice the different cases of factorization of polynomials. Please download it from here. For theory see here

Rational expressions and Functions: If you are still having difficulties recognizing rational functions and simplifying expressions, then please take a look at this chapter. I recommend reading through the explanations and examples and, after doing so, check your knowledge and understanding by working out the following problems:

page 494-495, Exercises 7.1. Problems 32 to 48, problems 55 to 66, and, problems 71 to 76.

Properties of Limits: For practice on the properties of limits, please take a look at exercise 12.2 on the Pre-calculus by Stewart, starting on page 897. I recommend doing the following problems: 1-8, 14, 15, 17-20, 25, 26, 33, 34.

Productivity and Planning

I came across this short video with tips on how to make your study time more productive. I found it very useful, I find myself doing some of those things myself for the things I need to study. Additionally, I found a nice blog that introduces several methods to keep track of your work and planning. I am currently using a modified Alastair method to keep track of everything I have to do, and so far it's been working very well. Hope you find these useful!
