I responded to you via PM. Here is a bit more just in case:
I think a Full Course may not be as beneficial as 5-6 personal tutoring sessions you can get for the same amount of money that will focus only on verbal (just a thought).
MGMAT and Veritas prep have good options, though some require you to purchase a package which defeats the purpose.
Also, have you used
MGMAT's books? If you have, you may want to raise it to their tutor and see if they can still help you troubleshoot your issues since
MGMAT relies on the same books in their course.
If you wanted to go much cheaper, you can go for the eGMAT course - only a few hundred bucks and focuses purely on verbal with a score improvement guarantee.
Let me know if any other questions!
