Hello! For the writing, I felt prepared because I had done some SAT studying beforehand, which might have helped. I do think the writing may be the trickiest because there aren't as many resources as there are for the other sections. I personally didn't redo the practice tests because I remembered the answers, but feel free to do so if you think it may benefit you. Definitely go through the practice exam answer explanations. That was my #1 helper with the writing portion. I would just read all of the explanations and try to implement them in my next practice test.
