Hi doitin,
As mentioned in the earlier post, I referred various sources for verbal practice. Since I was a bit weak in verbal, I made a daily routine of practicing around 25-50 questions of verbal. Practicing from different sources is important, as each book has its own distinct flavor of questions. for eg. one book may have SC that has more questions in Subject-Verb agreement area, while another book's SC may focus more on Pronoun errors. Practicing from various sources ensures that one is equally comfortable with all different varieties of questions.
(To reiterate from previous reply), For Verbal, I used (in order of importance, as per my experience)
OG 12(CR + RC + SC + Basics)
Manhattan SC (SC Basics)
LSAT papers (CR + RC)
OG 10 (SC)
OG Verbal(CR + RC + SC)
Kaplan 800(CR + RC + SC)
