Greenville Tech TeasV Prep Course

Has anyone taking the TEASV prep course at Greenville tech or anywhere else. At Greenville tech it's $219.00 for a 3 week course, twice a week for two hours. I afraid that without the course I won't be able to make myself fit in studying for it bc of my other classes. But I don't want to waste the money. So if you have taking this particular one or any other, let me know if you felt it helped and prepared you it if it was a waste of time.
