1. When you start a new notebook don't start at the very beginning. Skip a few pages. Later make a table of contents. That makes everything so much easier when studying.
2. When doing a complicated math problem, try wolfram alpha. It can explain the math problem and break it down to make math a lot easier.
3. When writing an essay, instead of using regular google try scholar.google.com. Google scholar focuses on scholarly literature instead available on the internet.
4. Instead of using a whiteboard use a picture frame and try erase markers. They save money and can look a lot prettier.
Anyone everyone I hope these hacks will help you with school! (I took all of these hacks from online and youtube videos.)
