hey,
i had the same problem a few days ago (i think you'll understand me when looking at my testscores) ..
RecommendationsRC: read some articles on
https://www.nature.com (not only the fascinating but also the boring)
CR: somewhere in the download-area of the gmatclub you'll find 100+x CR-questions, i downloaded them and solved them within 2 days, first time i really thought about an approach while solving CRs
SC: i read the
MGMAT SC book, but if you're running out of time (you obviously do so!) you should check the forum for slingfox' condensed SC strats.. i just reviewed them (too lazy to read
mgmat sc again) and they are a great refresher.. last 2 practice CATs i scored > 80-90% correct for SCs .. before i ranged at about 50%
By doing the above mentioned i was able to stabilize my V score (at least according to the last CATs)
Hope this helps u!
