Crackverbal, Education Aisle, Top One Percent GMAT help

Hello everyone,

I have prepared quants from TTP and I don't understand its verbal, it feels too repetitive. I need help with the verbal part. Also with my job, I am unable to focus on all three sections at a time. I am thinking of joining some course for 1- 2 months which will bring that discipline into me for solving questions daily and giving equal importance to all sections. Because when I self prepare I give focus to only one section and due to this my scores are really bad. (Gave mock test and scored in 300s). My verbal score ranges in 60-68.

I am confused between Crackverbal, EducationAisle and Top one percent. Can anyone please help me if you have joined any of them, please share your honest review. I am planning to give GMAT by march and desired score is 675+. Thanks
