About the Weekly Mastery Lectures for Math 123
Linear Algebra and Probability (McGill, Winter 2018)
The weekly sessions for Math 123 are 2h, smallgroup, sessions that aim to clarify the concepts and theory presented in the class lectures and tutorials. They include detailed, typeset notes (written specifically for Math 123 at McGill) that explain the terminology and notation. The notes are carefully designed as interactive documents that provide students with a chance to engage the material during the session and also include representative problems and additional practice problems whenever possible.
During the session we will look at detailed, developed solutions, that illustrate different aspects of the material in a systematic, structured and easytofollow way. Solutions are colourcoded to make it easy for students 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!).
The sessions are also designed with a view of the entire course in mind, with the goal of helping you know where to invest your time – both in order to succeed in the class, and to know which topics have the greatest application outside of this course. Most importantly, you’ll master topics as they are presented so that you won’t be stressed when the final arrives.
The Math123.com Weekly Mastery Lectures will help you with:
 Time Management: although able to learn and understand the material on their own, many students attend the weekly tutorials because it is the best use of their time. The notorious difficulty of McGill classes is not inherent to the content itself; rather, it is the sheer volume of material which makes the classes difficult. Better to spend 2h in a weekly session that will help you really understand the concepts and complete assignments yourself than to spend 810+h banging your head against the textbook and trying to decipher online resources only to get answers that don’t really make much sense to you, and have it haunt you later in the semester when you’ve got 4 other classes to study for.
 Maintaing Commitment: despite the best of intentions to keep up with material and not use Uncle Wolfram for Webworks, McGill & Montreal have their way of always offering up absolutely, totally, 100% legitimate reasons that derail the best laid plans. So you make a financial commitment to a weekly session that helps you reach your goal. It’s like the gymmembership model: you can workout on your own, but it’s a lot easier to reach your goals when you surround yourself with others who are working towards the same end. Knowing that you need help to reach a goal (& acting on it!) is knowing how to find the success you want.
 Math Therapy: I believe that anyone who wants to learn math, can. If you feel you’re terrible or hopeless at math, or just don’t enjoy it, there’s probably a list of bad math teachers somewhere in your past that would go a long way to explaining the difficulties you have, & no one wants to spend their time feeling like they just can’t get it. However, if you’re motivated and willing to do the work and practice, then you can definitely succeed. I’ve seen it hundreds of times: students go from failing in a fantastically impressive way to acing the class. The weekly tutorials will go a long way to rehabilitating your relationship with math. Whatever your level, I want to help you reach your goals in this course – there’s so much more to gain than just a good grade in rising to the challenge.
 Top of the Class: many students who attend the weekly Mastery Lectures don’t want to just pass the class, they want to understand the material at an intuitive level, &nd they want to ace the class. The weekly lectures provide a wealth of information that help you develop general, transferable skills in mathematical literacy and reasoning, and I work hard to help students do their very best (and many have both aced their classes and finished very top of the class).
Cost & Payment Structure for Math 123 Weekly Mastery Lectures
If you have never attended one of my sessions previously, you can check out a Weekly Mastery Lecture for only $20. Simply register using the contact form above, or get in touch with me at Jacob@Math122.com – you’ll be glad you did!

Full 7Week Membership: prepay for the entire set of 7 sessions and get the lowest price offered for the Weekly Mastery Lecutres: $280 for everything you need to master the material and succeed in your class.
Included in the weekly membership: not only the weekly lectures, but detailed notes at every session (46 pages, 9pt, colourcoded), and priority registration (as well as discounted rates!) for WebWork Workshops, Midterm Review and Final Mastery Sessions.
This option is only available during the first 3 weeks of sessions and for the total set of 7 sessions. So if you join during the 2nd or 3rd session, the price is still $280; however, you’d receive all the previous notes and still qualify for all the benefits.
My goal in offering this lowest price is to encourage you to join the sessions early, so that you can establish a strong foundation right from the start so you’ll be less stressed for the final and do better in the class, overall: take advantage & register right away!
 Prepay (min.) 4 Sessions: $55/session, total $220, includes notes. There is always the option of getting the notes from previous tutorials, sutdents can contact me at Jacob@Math122.com for exact prices. The same benefits as the 7week membership also apply, with the exception of discounts on the WebWork and Mid Term sessions. For complete details, get in touch using the contact form or contact Jacob@Math122.com.
 Individual Sessions: $65/session, subject to space. Cancellations must be made min. 48h prior to the session. For additional information, get in touch using the contact form, above.
N.B. All payments are nonrefundable; for additional details, please contact Jacob@Math122.com.
What You Should 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 so that as the midterm approaches you’re able to focus on refining your understanding as opposed to getting your first exposure in a crashprep session.
Part of the longterm 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 relearning everything come the midterm and final exams.
Whether you join the weekly sessions 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.

What others are saying about our sessions:
Finding the right teacher is really important, but it’s not easy to know what to expect. Here are some unsolicited comments from recent McGill students. Ask around: I work hard to make sure that all of my students do the best they can!
“I’d just like to let you know that I got 100% on my MATH 123 final, and got 100% in the course. I really appreciate your help, I couldn’t have done it without your sessions.”
– Trevor Thorburn, Math 122 & Math 123
“I just wanted to let you know that the math exam went really well. I got 90% on the multiple choice and 96% on the long answer. I’m really happy with how it went and wanted to thank you again for all your help this year!”
– Hillary EvansKrstajic, Math 122 & Math 123
“Thanks for all your help you were a life saver!”
– Spencer Bromley, Math 122
“I know most people are probably Grieveing for their grades right now but I found the final difficult but manageable.
Just wanted so say thanks for the help this semester with ODES. The emphasis you put on theory was extremely useful for this class especially on the final.
Thanks again Brodry for the time and effort you put into the sessions and I’ll definitely recommend you to anyone looking for a math tutor. Also quiz apparently went better than I originally thought: I got 100%!”
– Laurent G. MATH 263 Fall 2014
“Thanks again for all the work you’re putting into these tutorials. It’s really making a difference as far as learning and really understanding the material goes … Jacob is an excellent instructor. He takes care to ensure we truly understand the material and can derive the equations needed on our own.
His sessions are clear, concise, and engaging, much better than any materials supplied by the professors or math texts.
I highly recommend him to anyone having issues intuitively understanding the materials in class.”
– Zachary K., MATH 263 Fall 2014
“Just wanted to keep you updated as you asked about my grade! I ended up getting an A which I am extremely happy about so thank you again so much for your help, would have never been able to do so well without it!”
– Cassie E., Winter 2014
“Got an A! Thanks for the help I’m so relieved woooooow!”
– J. Arnette, Winter 2014
“Comparing my Calc 1 results (C) and Calc 2 results (B+) all I can say is you saved by butt! and I am very grateful for that. Thank you!!!!”
– Dana M., Winter 2014
“I passed. Literally almost threw my computer in the air I was so relieved. I’m pumped – Thanks so much.”
– A. Singh, Winter 2014
