What are the best blue book tests to do?

Last night I did a livestream on the second channel. Like usual, I did "SAT questions until I get one wrong." Ultimately, I lost on a hard Transitions question. It was a really niche question, where the word "thus" worked, but the sentence right BEFORE the blank was not a clean cause-and-effect, while the rest of the passage was. Therefore, "thus" or "nevertheless" could have both technically worked, and I (and the chat) chose wrong. Basically, it was weird. And the question made me realize something: This was a concept you NEVER could possibly understand from a YouTube video. (You probably didn't even understand my explanation of it above lol.) This was a mistake you could ONLY understand by actually GETTING A QUESTION WRONG and then examining it afterward. (Like I did lol.) It's just too ultra-specific and weird for someone to ever understand without trying it. These are two underrated benefits from doing practice questions: 1) You realize things you NEVER wouldn't learned otherwise 2) When you get questions wrong, the PAIN of missing the questions is actual encouragement to improve I (and the chat) experienced both of these last night. And you can experience it EVERY time you do practice questions. So, the next time you're doing questions on a website like Aniko, remember that this is the goal: Identifying niche concepts and making sure mistakes don't repeat. New stream tonight, too, by the way.
