Hi,
Rather than directly going to solve questions, I suggest you strengthen fundamentals.
First identify which is your area of concern. Is it SC, CR or RC?
If SC is your area of concern, learn fundamentals with GMAT club grammar book or
MGMAT verbal foundations
For RC and CR, you may refer to
MGMAT strategy guides.
Learn the concepts, shortcuts and fundamental rules and then try to solve the questions.
Start with easier questions. You can find a whole directory of questions in gmat club using the directory search.
