Though I don't remember what I scored on each test individually, I can give some estimates.
First Power Prep test and first test in official GRE book: Q 158 (ranging 155-158 throughout all tests), V 169 (ranging from 165-170)
Actual 1: Q 155, V 162, AWA 5.0
Actual 2: Q 158, V 164, AWA 6.0
I studied for this over 6 months, so it was pretty disappointing to see my quant scores barely improve. I thought the first Power Prep and tests in the GRE book were much easier than the actual test. I thought the Magoosh questions were a little more accurate, difficulty-wise. I performed much worse on verbal during the actual test. The first section was very easy both times, but I found the second section to be VERY confusing both times. It wasn't that I didn't understand the vocabulary, but I just found the wording of the questions to be unclear. If I had unlimited money, I would consider experimenting with purposely getting some questions wrong on the first section to not move onto the advanced section for my second verbal section. However, that's a huge risk for a test that is so costly. If you plan on doing very well in the verbal, practice with Magoosh questions set to Very Hard.
For the AWA section, I got lucky the second time around - for my issue task, which I always found more difficult, I got a prompt that meshed well with my actual interests and was therefore easier for me to write about. Seeing my scores for both tests, it seems that writing more definitely helped. Being a fast typist may be an advantage.
