I really liked EK 1001 in all the subjects except Physics. For Chemistry, I thought it was very good at really solidifying the concepts so they became second nature to you. Even though they didn't have passage based questions or particularly tricky questions, I think they did a very good job and teaching you the basics and everything you should know. If you have time then I would suggest do it. Skip the physics though, I thought it was nothing like the MCAT and was much more like textbooks questions than general knowledge MCAT style questions. They had too many complex concepts with too many difficult calculations. In my opinion, I wouldn't recommend that EK 1001 Physics to anyone.
Hope this helps,
