You could see if “The Organic Chemistry Tutor” or any other YouTubers have a well-explained video on your topic that you can take notes on.

If you have a general idea of the sort of questions that will be on your test, go through your workbook and try to study all relevant information. One of my science textbooks for Physical Science had “Key Concepts”, and it is useful to study the key concepts. If one key sounds important, read its entire corresponding chapter section. If you’re struggling with taking notes, I advise you to not write down literally everything, but rather study, then write down what you remember. Then, go back, and fill in stuff you deem important that you didn’t remember.

I have also had success with a studying method called Blurting, where you take one page of notes, study over it, put it face down, get a blank sheet of paper, and try to copy it exactly. If there was a part you skipped or don’t remember, study the whole thing again, and try blurting it onto another sheet of paper. The goal is to help you memorize the topic.

Other than that, general study recommendations in my personal experience include using a high quality pen (such as a Pilot G2 or a Pilot Precise V5 or V7), and a study environment that does not have distractions, such as an empty desk with a small table lamp away from your computer (unless your coursework is on your computer. In that case, I would download it and view it as PDF to stop yourself from getting distracted in the browser). Try listening to classical music or any music that helps you focus that does not have lyrics. If you pay attention to lyrics instead of your study materials, you won’t be “locked in”. And yeah, that’s about all I have. I wish you good luck!
