I use a mix of videos - FI I always preferred Arif and for the rest I used Sch. I use the FQ summary, but for L3 majorly studied from the CFAI text. For AM portion, I practised Sch, Arif and FQ - I found them all useful because I got used to different styles of questions though the content in all the three were almost similar.
Please take this idea for whatever its worth, since I dont know my result yet
In between dropped you a note confused2010 and CFAfatso!
Edit - CFAfatso - the email I sent bounced!
