Struggling to understand what is happening in Comm 341?

I promise you it's not that hard. You just need someone to show you how to breakdown the problems. (That someone is me!)

  • Master when and where to use each formula to avoid silly, but costly mistakes.
  • Learn the common exam tricks and practice them on my mock exams so you are exam ready!

Yes, It Really Is Possible!

The All-In-One Pre-Midterm and Midterm Review Session

Video Poster Image

This review session contains:  

  • Everything you need to know summarized into 15 pages for the pre-midterm (6 additional pages for the midterm).
  • The course concepts quickly and efficiently explained so that you finally know what is going on. I will show you how to solve the problems and WHY we are solving them.  
  • Tons of practice problems (with the solutions separate so you can actually practice the whole problem).
  • Two mock exams that you will HATE while you are working on them but love when you are kicking butt on your exam.
  • Q&A Sessions before the pre-midterm and midterm so you can ask any and all questions. 

What do you need to know for the exam?

MODULE 1 (Pre-Midterm)

Little's Law

Little's Law is the basis of most of the concepts in Comm 341. These questions can look decievingly simple, but them all of a sudden you have a full page diagram of arrows, triangles and no idea what to do next.  I will show you:

  • How to figure out what actually goes in your diagrams and what is meant to confuse you
  • How to handle any curve balls
  • How to (simply) calculate profit/costs for these problems (think tuxedo) 

A monster Little's Law problem shows up on every midterm and final. Don't skimp on this. 

MODULE 2 (Pre-Midterm)

Capacity Analysis

How many times have you wanted to know the maximum number of widgets you could produce per hour but you just didn't know? Don't worry - I am here to help. I will teach you to: 

  • Calculate unit load, capacity and determine the bottleneck
  • Use utilization and implied utilization to make an informed analysis
  • Work with single product and product mix problems

You’ll be a master of any capacity problem in no time. 

MODULE 3 (Pre-Midterm)

Batching/Flow Interruptions 

Anyone else hate the term "flow interruptions"? No, just me? Well regardless, I will use making cookies to explain the concept of batching. SPOILER: it doesn't work the way you think it should. I will show you:

  • How to use the two key formulas properly 
  • How to draw those annoying inventory graphs from BDM last year (yep, they are back)
  • How to not screw up the unit load calculations for batching

Again, I will use cookies in my examples, so that is already better than what you had in class. 

MODULE 4 (Midterm)

Waiting Line Analysis/Queuing Theory

You can also call it resource pooling. Whatever you name it, it's about balancing the needs of your customers and the capitalist drive for profit. This will be the concept covered between your pre-midterm and midterm.  I will show you:

  • How you really only need one formula because they are all the same 
  • How to figure out what the question is asking and how to answer it (well...isn't that the point of exam review sessions) 
  • That the answer is always to have 1 common line and allow people to proceed to the next available cash (ie those monster line ups at the bank or Walmart) 

I hope you appreciate the sass on this page. Someone told me I needed to put together a whole "sales page" thing. What do you think? 

This Exam Review  Is For You If...

  • You are confused by class (right now) but you are ready to figure this out
  • You aren’t sure what to do when you look at a practice problem (right now)
  • You want to have a clear study plan for BOTH the pre-midterm and the midterm 

I'm Doulton Wiltshire

After graduating with my BComm a million years ago, I started tutoring. For the last 10 years I have worked with over 3000 commerce students. Because I start working with most students in first-year by the time you get to third year I like you too much to abandon you while you take operations even though I dislike this course. (Ironic because my Masters degree was in operations - ugh we all make bad life choices at 21). Over the past 5 years, I have helped SO MANY Commerce students get through ops with a smile on their face and an A on their transcript. These concepts aren't bad, they just need to be broken down well.
