Physics Sensei questions & answers
How Do I Study for a Class with No Study Guide?
Your professor says the exam is next week. Someone asks if there’s a study guide. The answer: “No. Everything we covered is fair game.”
Everything? That’s six weeks of notes, slides, and homework. You don’t know where to start, so you start at page one and hope you get far enough.
Studying for a class with no study guide feels impossible. But the study guide isn’t missing. It’s hiding in plain sight, and you can put it together in about an hour.
What’s really going on
Professors give you clues about the exam all semester. The topics on the syllabus. The examples they work in class. The homework they assign. The quizzes. The things they repeat, or say “this is important” about.
Most exam problems look a lot like those. A study guide would just collect them in one place. You can do that yourself.
Why studying everything makes it worse
Without a guide, every page feels equally important. So you give every topic the same amount of time, starting from the beginning.
That means the big topics get the same time as the small ones. And the topics at the end, often the newest and hardest, get the least time of all.
Why it’s hard to change
Making your own study guide feels like extra work when you’re already behind. It’s tempting to skip it and just start reading.
But an hour spent sorting saves many hours of reading things you already know.
The fix: build your own guide, then test it
Spend one session building the guide. Then let it tell you what to study.
Try this a week before your next exam: the topic map
- List every topic from the syllabus or the lecture slides. One line each.
- Next to each topic, write down one example from class and one homework problem on it.
- Star the topics your professor spent the most time on, repeated, or called important.
- Do one problem per topic, notes closed. Ask: What are they asking? What do I know? What’s the big idea? Mark each topic green (got it), yellow (shaky), or red (stuck).
- Study red first, then yellow. Within each color, starred topics come first. Save green for the end.
Now you have a study guide, and it’s better than one your professor could hand you, because it’s built around what you don’t know yet.
What changes
The first time, building the map takes about an hour. After that, you can keep it going all semester: add each new topic as it comes up.
By exam week, you’re not starting at page one. You’re starting with your red topics, the ones that will actually move your score.
No study guide? Make one that fits you.
Practice problems built for this
On Physics Sensei, problems are organized by topic, and every one is solved step by step with the same questions you just used. That makes it easy to find one problem per topic for your map. Each one asks you to try it first, then gives you one more like it, with new numbers.
Your next step: make your topic map for your next exam. Use Physics Sensei to find one problem for each topic, and do them with your notes closed.
