After failing the core knowledge section (and consequently the whole lab) on my first lab attempt while doing lab over 90% I decided to use INE's Core Knowledge Sim to refresh my memory and boost my confidence in this area for my second attempt. This product was just what I needed (and a bit of luck, of course) because I had enough experience for the lab section. Although core knowledge questions I had on my first attempt were much harder to pass than on my second attempt, I'm very glad I invested some money in the Core Knowledge Sim - it is a great product.
