It sounds like this group is pretty determined! But for those prospective examinees who struggle with verbal, I recommend (as always):
BOOKS:1. Manhattan SC - Quite simply the best out there. Read this at least twice, preferably three times.
2 (a). Powerscore CR - Fantatstic product. Easy to read, informative, and extremely helpful.
2 (b). Powerscore LR - If you truly need to toughen yourself up, or simply enjoy pain, then opt for the LSAT LR guide instead.
3. Powerscore RC guide - Better than the Manhattan RC book. It contains over 100 RC questions and some practice exercises.
4. LSAT Superprep - This book has 100 RC questions and 150 LR questions. If you have time and need extra practice, then this is a decent source.
QUESTIONS:1. OG Verbal
2. Brutal SC series
3. Manhattan online tests and questions banks
4. GMATClub forums
READING PRACTICE:1.
GMAT Fiction - Read at least 500 - 1000 pages worth. This should be seen as a nice way to wind down your day and still sharpen your RC and SC skills.
2.
The Economist - Try to read an article every day. Very good practice for the GMAT and business school.
For Powerscore, make sure to pick only
ONE guide: LR or CR. Studying both is not a wise investment of time, energy, or money. In my opinion, the CR guide should be enough. Also, GMATClub forums are a treasure trove of questions. Use this to your advantage!
My list may be unrealist in its entirety for some with hectic schedules, familial and job obligations, and so forth. Still, try to squeeze in as much as possible. For instance, avoid TV, and never go to the bathroom without a book in your hand to pass the time.
Good luck!
