Need help regarding gmat verbal

One thing that I have noticed is "Don't move away from the official material" for verbal. I am fairly good at quant and I need serious help for Gmat Verbal as this test is killing me and destroying my peace I can't seem to handle the fact that I have so little of these questions and have limited ways of getting better at them. If anyone has any other way for me to improve please say so. I need some questions that I can burn and understand where the mistake lies and GMAT explaination sucks. BTW I am a non native speaker and I am most fed up of CR. I have tried Gmatclub Charles, but I get basic advice like read the question and question stem that's not helping at all . I need a road map for what to do how to attack .
