HI Vikhyath,
You should take advantage of the Forums here and post the specific questions that are giving you trouble. There's also a pretty good chance that someone else may have already posted those same questions, so you can search them out here.
The explanations offered by most GMAT Books (including the OG) tend to be 'technical' in nature, but most GMAT questions can be solved in a variety of ways. As such, you might need to learn (and practice) some new tactics to help you improve on the question types that you're currently not great at.
How long have you been studying?
What resources have you been using during your studies?
