In this video I go through how to break down molarity problems (pulled from an actual general chemistry 1 exam), and understand the relationship between molarity, moles and molecular mass. On the surface it seems like a very straightforward problem. There’s not a lot of work involved here. But if you’re not solid on it Continue Reading

## 3 Ways to Make Breaks Between Classes More Productive

We all know how awkward it can be to figure out how to use your breaks between classes. But let’s be honest about something. Everybody always wants to know: How can I be more productive? How can I study more in less time? How do I get time back so that I can do things Continue Reading

## Rotational Motion Torque Problems (Physics 1 Exam Solution)

If you don’t know what you’re doing, solving rotational motion and torque problems for your physics class can get ugly. Here’s the scenario: You’re finally starting to get comfortable with the idea of velocities, acceleration, force, and momentum. You can do this in both X and Y: projectiles, blocks sliding down slopes, ropes and pulleys Continue Reading

## Area Between Two Curves (Calc 1 Problem Solution Breakdown)

Finding the area under a curve is a basic Calc 1 concept, but finding the area between two curves is a bit more difficult. In today’s video, I go through a problem breakdown from a Calc 1 exam where we’re asked to find the area between two curves. Here’s how to do it, step by Continue Reading

## My Hardest Engineering Class (Fluids): 3 Big Lessons Learned

What’s the hardest engineering class? It’s a long-standing debate, but personally, fluid mechanics is what killed me. We all have that one class that we regret. That whenever we think about it we get a weird gross feeling in the pit of our stomach – like we just ate some old takeout from the back Continue Reading

## How to Avoid Falling Behind In School: My Top 3 Principles

So you just finished a huge marathon session yesterday. You’re pretty tired, but got all caught up on your backlog of coursework. Now what do you do? In the last video we talked about how to catch back up on a backlog of coursework by using a blitz day, but we really didn’t cover the second half of Continue Reading

## Riemann Sum Problems (Calculus 1 Exam Solution Breakdown)

Approximation methods can be tricky. In this video, I go through the method behind Riemann sum problems using an actual exam solution (a right-hand sum). Finding the area under the curve is something that we talked about all the time in Calculus 1 but when we’re finding that area, why do we actually do it Continue Reading

## Related Rates Problems (Calculus 1 Exam Solution Breakdown)

Why do all related rates problems involve cones filled with water or ladders sliding down buildings? In this video, I break one down from a Calc 1 exam solution using the Reverse Learning Technique. Related Rates Problem Statement A conical paper cup 3 inches across the top and 4 inches deep is full of water Continue Reading

## How to Catch Up On Coursework (AND Keep Up In Class)

Picture this… Each semester starts out AWESOME, and you’re pumped because you get to work with clean slate, but somehow you always end up falling behind and never really manage to catch back up. Well turns out that’s EXHAUSTING, so this time you want to make some changes. You finally decide to get your shit Continue Reading

## Tension Problems (Physics 1 Exam Problem Solution)

Physics tension problems can get extremely confusing if your method isn’t rock solid (especially when you’re a little sleep deprived). And if you’ve ever been in a similar situation to this physicsforums commenter… Then you already know what I’m talking about. So below I’ll go through a solution to a tension/Newton’s Laws problem pulled from Continue Reading
