These are the GMAT verbal books I recommend:
–The Official GMAT Guide 2021: https://amzn.to/3aGTUz8
–The Official GMAT Verbal Review Guide 2021: https://amzn.to/3cJQkH8
–Manhattan Prep's Sentence Correction Guide: https://amzn.to/39QbHV3
–Powerscore GMAT Critical Reasoning Bible: https://amzn.to/3sKix5p

Everything you need to master the GMAT Verbal can be found in these guides, on GMATClub, and on YouTube. I highly recommend that you spend your time teaching yourself the basics of the GMAT, and only reach out to a tutor (or enroll in an online program) if you've gotten as far as you can on your own and are stuck. 🙂
