ipasscpa on "Beckers 2012 material for regulations"

I have read in the previous posts that Beckers didn't do a good job on REG. Lot of people mention about "Ancillary" material which I did not come across yet. I am on REG 2 of beckers 2012. Is there anyone out there who used Beckers 2012 and passed the REG part without supplementing with any other review course? where is that ancillary material?
Thanks in advance
