Welcome to Jacob’s Online Help Desk for Math 123 Linear Algebra and Probability for Management at McGill (Fall 2020) taught by Prof. Erin Beckman. Here you can get in touch with me and find information about my sessions.
- Everything you need you know about Math 123
This is very satisfying class to teach because a good teacher in a smaller learning environment can make a huge difference.
Although the class starts off pretty slow and easy, students often get caught off guard when it comes to the midterm because although they understand individual ideas or steps in the solution, they aren’t as comfortable interpreting the meaning of their results. As with any math class, this is easily avoided if you keep up with the class throughout the semester. Then, as the Midterm approaches you’re able to focus on refining your understanding as opposed to getting your first exposure in a crash-prep session.
Part of the long-term challenge in this class is that, unlike Math 122, the course concepts don’t build on each other. Instead, you’ll study several units that are effectively completely independent of each other. While this gives you 2 or 3 chances to get a fresh start with a part of the course, it also leaves you open to forgetting or ignoring large chunks of the class. In the weekly sessions, I include regular review and practice problems from all sections to keep you fresh on all the material so that you’re not left re-learning everything come the midterm and final exams.
Whether you interested in doing sessions with me or not, if you want to do well in this class, push yourself to really understand each topic and concept as it comes up, and be sure to circle back on questions you found challenging when the class has moved on to other topics. Don’t be satisfied with just being able to get the right answer for your WebWork assignments, that won’t be enough. Maintaining your understanding of each topic will make the end of the semester much less stressful for you, leaving you with more time to focus on other classes.
- About Math 123 sessions with Jacob
My Math 123 sessions will help you master the concepts and theory presented in the course lectures. They include detailed, typeset notes that explain the terminology and notation. The notes are carefully designed as interactive documents that provide you with a chance to engage the material during the session so you can test your understanding, and also include representative, fully-solved problems and additional practice problems.
During our time working together, we will look at detailed, developed solutions, meant to illustrate different aspects of the material in a systematic, structured and easy-to-follow approach. Solutions are colour-coded to make it easy for you to see through the barrage of symbols and focus on the key concepts. It’ll also help you learn to structure your answers efficiently and effectively, so that the logic of the solution is clear to you (and the marker!).
