I took advantage of Jeff's free Blitz trial about a month ago for FAR – if you are in cram mode, I would HIGHLY recommend it! I procrastinated for 6 months and ended up throwing one heck of a Hail Mary before my NTS expired – I think I studied for a solid week and a half in a two week period leading up to the test. In the interest of full disclosure, I ended up with a 72; however, Jeff goes over a bunch of calculations and concepts that stuck with me on exam day – stuff I hadn't understood or fully grasped while cramming with Wiley the test bank and Yaeger's CRAM videos. It brought a lot of things together that really helped out on exam day – I really think I would have scored much lower had I not gone through all of the Blitz videos.
P.S. Jeff, if you're reading this – thanks!!!
