I received almost the same score
Math - 162, Verbal - 159.
Was preparing for 3 months, had a lot of pressure from work and family, so could not concentrate on GRE only, was lazy all the time, so my score is so much high, but not the best. The only time I had for preparation was way after midnight, when all of my kids went to sleep and I am not distracted at work.

I am not a native speaker, but I had bachelor degree from US university long time ago (TOEFL at the time 600 paper version, GPA 3.2).

Here is what I used to prepare for GRE:

Verbal part -
1) I found this app PAINLESS GRE for android very usefull tool to memorize and test yourself of new words (set RANDOMIZE, and 15 words per session, plus old words ratio to 80%). With it alone I learned 100-150 words (not only memorized, but also know them in context thanks to this app).
2) Watching Big Bang Theory TV (TBBT) series with later reading transcripts from here bigbangtrans. wordpress. com is another way to increase your vocabulary with obscure nerd words.
3) I downloaded podcast JUST VOCABULARY from south africa, which had 500+ podcasts each featuring two GRE words. To combine with PAINLESS GRE app, I "cut" each word and matched it with current set of words, which I was learning with PAINLESS GRE and also in TBBT. They audio file are very handy to listen while you're traveling, re-inforces your memory of new words.
4) I read NYtimes articles every day, esp. in SCIENCE, ARTS, BOOK REVIEWS, OPINION, ROOM FOR DEBATE sections. (the last one is good for AWA)

For math quant, I used the following:
1) Magoosh video course was extremely useful to refresh memories of math, esp geometry, combinatorics, etc
2) Manhatten 5lb practice book - just do all the match problems, even in chapter 30, advanced math. You will notice the results soon. (did only math sections, skipping the verbal ones).


FOR AWA - I found Magoosh video in Writing just excellent, also read article of UNC writing club on fallacies (writingcenter unc edu / handouts)
Also downloaded the list of topics for arguments and issues, and then tried several of them at random, then compared with what other wrote to see if I missed anything. There is a general layout for both argument and issue essay, you just need to find it and practice it on real questions.

For exam practice:
1) took 1st official GRE practice test
2) took 6 Manhattan practice tests (chose always VERBAL + QUANT only option, without AWA simply because I did not have time)
3) took 2 Kaplan practice tests (there were actually 6, but I did not had time to do them all, besides Kaplan's one are the longest, as they contain experimental section, which is not present in GRE official practice, but is PRESENT on real test!)
4) finally took 2nd official GRE test

Results of practice tests:
- Manhattan free test - 160Q / 154V (taken with 1.5x time)
- Official PowerPrep II First Test - 159Q / 151V
- Manhattan 1 - 155Q / 154V
- Manhattan 2 - 156Q / 154V
- Manhattan 3 - 160Q / 157V
- Manhattan 4 - 159Q / 156V
- Manhattan 5 - 160Q / 152V
- Manhattan 6 - 160Q / 154V
- Official PowerPrep II Second Test - 160Q / 153V
===========================================
- Real Test 162Q / 159V / 3.5 AWA

The real test I found to be somewhat easier than Manhattan, and way easier than Kaplan's (Kaplan's tests had in 2nd quant lots of stats and combinatorics questions, i did not see so many on the real exam).

PS. I have to add some notes on time management. GRE included excellent feature of MARKing any question, so that you could return to that question. If you stuck on some question, do not hesitate and waste time, randomly select the answer (say C) or type any number (say 2) or fraction (say 1/2), press MARK and go to the next question. You will notice that with proper time management, you will always have some time left before the timer for the section ends. I used this time to go back and review those difficult question.
