This is honestly pretty embarassing to admit, but as I study for the reading portion of the SAT, I've found that I struggle the most with questions that pertain to when I'm supposed to use a specific style of punctuation. Ex; using a dash over a comma, or a semicolon over a colon. Are there any good resources that would help me improve this?
i would recommend going to the yt channel "penguintestprep" (or smth like this) and check the video about the grammar or you can also watch the video of James Lu about the grammar breakdown
also you may find useful the "sat walkthrough" videos as you will see which and how strategies are applied in the real situations
One option you can check out is grammarbook.com
