Today, I canceled my GMAT appointment and lost 250$, because I could not sleep last night and felt that I was not in the clear mind in the morning

(((. So I decided not to spoil my attempt and improve my verbal a bit further!!!
So I am back to my preparation:(((!!!
My CATs results (in chronological order):
GMATPrep1: 640 (Q46;V32)
GMATprep2: 620 (Q48;V27)
GMATPrep1 (reinstalled): 720 (Q50;V37)
PopwerPrep1 (most verbal staff from the OG, so consider it urepresentative): 730 (Q48;V42)
PopwerPrep2 (most verbal staff from the OG, so consider it urepresentative): 730 (Q49;V41)
GMATPrep2 (reinstalled): 660 (Q46;V35)
I need to improve all verbal parts till 42+. What materials would you recommend to use (except for Kaplan GMAT800, SC1000,
MGMAT SC): SETS, GMATTER,...???
What CATs would you recommend to do which are most close to GMATPrep and PowerPrep?
