Okay so call me a forgetful dork but I took notes while studying for the math section of the SAT with Khan Academy yesterday

Shoutout to @aredhel-of-gondolin for helping me study! If you tend to get distracted easily, I would recommend asking a friend to review with you. Personally, I feel a lot more focused when I study with other people, even if they’re watching tv and talking to me about it while I do work.

I used GoodNotes 5 to make these while I was studying. I love how Khan Academy tracks what you need to study more and gives you both videos to teach you and practice problems to make sure you understand. Sometimes, Sal’s way of teaching gets a bit confusing for me, so what I like to do is pause the video after he introduces the question and write down the important information. Then, if I understand it well enough at that point, I go ahead and try to solve it. If I get stuck or don’t know where to go, I play the video and stop right after he explains what I’ve been confused on. Then, I see if we got the same answer. If my answer is wrong, I go back and follow along to see where I got something wrong and try again from there.

I find that using a specific color to highlight important information/answers helps me remember it better when I’m reviewing! I thought this shade of blue was really cute as a preset highlighter but it didn’t have a matching pen color, so I went to “custom” and put in the same HEX code as the highlighter.

To give the titles a bit of a pop, I wrote them in black, selected and copied the text, pasted it at a slight angle from the original text, and changed the font to my highlighting color. This gives it a bit of a shadow effect and makes it really eye-catching. If you want to use white, go for it!

When you take notes to reference later, make sure you include all necessary information that helps your end result make sense. If you don’t know why your answer was wrong, always go back to the original question and make sure you’re answering exactly what the question asked.

Remember that your notes are for you. Don’t be afraid to write important information you might forget and need help remembering in the margins! I know I definitely did for a few of those pages.

Good luck!

Steps for Solving Exponential Equations

1. isolate the exponential expression

2. use inverse properties      -->  log(b)B^x = x

3. solve for x

4. check solution
