I think we can all safely agree: Homework (especially those ridiculously long WebAssign problem sets) can be a royal pain in the ass. It takes forever to finish. It leaves you feeling tired, frustrated, and wondering whether you've actually learned anything at all, despite all that time you spent in class. It was created by… Continue Reading

We all know finals week (in all it's stress inducing glory) is the most crucial time of year. But does it have to be so insane? I say no, and here's why. Finals is the time of year that you need to focus the most. The large majority of your grade is about to be… Continue Reading

Does reading through gravitational potential energy examples in your textbook make your brain want to explode? In this video I break down a Physics 1 exam problem that covers gravitational potential energy, orbits, escape velocity, and all the relationships between them that you'll need to know. A space station of mass 400,000 kg, orbits the… Continue Reading

All of us want to know how to focus on studying consistently, but often it's almost impossible to do. Want to know how to do it, and why willpower is the key to staying focused while studying? We'll cover that in this video. Click here to download the free "Stay Focused While Studying" PDF Quick… Continue Reading

What are some good places to study? Does study environment matter? The research is in, and what it says is quite interesting... So in today's video I answer a question about whether there's actually such a thing as a "best" study location, or whether you're just as well off on the couch. Then, I'll offer… Continue Reading

Change in momentum problems usually involve figure skaters, bullets, and other ridiculous scenarios. But don't be fooled by the flash and dance - there's a method to the madness. And in this video I go through an example of a conceptual change in momentum problem from a Physics 1 exam, step-by-step. Download the full Change… Continue Reading

Physics 2 (electricity and magnetism) can be a cruel bitch of a course. Download a free PDF copy of this post to take with you If you've ever come across a circuit with a resistor, capacitor, and inductor in series with some sort of complex switching mechanism in between them, and then are asked to… Continue Reading

Most of us want figure out how to pay attention in class more often, but it's tough, especially during that horrible, boring lecture you've got coming up next. So let me know if this sounds familiar... You're sitting there, and the professor is scribbling non-stop on the board. Symbols, diagrams, equations; you really have no… Continue Reading

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
