This is a free sample for students interested in joining PLEM University. In this "Problem Solving Session," we looked at how to approach exam taking while keeping within the textbooks and literature. Research Member Sessions • Practice Research [Basic to Advanced PLEM Textbooks] • Unsolved Problems • Original Research • Group Mentorship Meetings • Job and Resume Meetings We do the above meetings on rotation and at random—depending on the time of year or my schedule. You are notified when meetings are held ahead of time when done at random. All lessons are saved for Research Members only via https://plemuniversity.com/ The rate is currently $99/month (cancel anytime) but will be teared as more students join as I cannot overload myself.

Before we begin, we will locate a textbook and take a look at it. It should be known that Algebra with Trigonometry or College Algebra and Trigonometry are the same exact books as a standard Precalculus textbook; only, they may—on occasion—have an introduction to limits in calculus in the last chapter. This depends on the textbook/author.
Precalculus is essentially just a more elaborate version condensed into one semester of both algebra and trigonometry. Meaning: it is a review course but at a more complicated level.
