I wish I had ONLY paid for Seperac, because both Barbri and Pieper ended up being sort of a waste of money, ESPECIALLY if your law school offers a bar refresher course your final year. It may be too late for you, but for anyone else out there, take your law school's 3L refresher course and make your outline awesome and you sir will save $3,000.
As for Seperac, his stuff is extremely comprehensive and thorough. I never met him, but he is a real human being and I did email with him extensively. He is King Nerd when it comes to statistics and he knows his shit. The statistical analysis helps the most when it comes to figuring out what to study and how to budget your time. The NY Bar sucks so much balls because there is NO way you can possibly study all 30+ topics in depth and know them enough to write NY Essays without having a photographic memory. Anyone who says otherwise is full of shit.
The trick to the NY Bar is to study the topics most likely to be on this year's bar exam, and Seperac does this BETTER than Pieper, who I used to idolize for his predictions. Pieper is good, but after I saw Seperac's website I realized that John and Troy and Damien are just guessing. Seperac has sat down like a psycho and went thru every past NY essay and his outline breaks it down by percentage of likelihood of the topic appearing on this year's exam. And that's just his NY stuff. The MBE sections are what I really needed, because he also breaks down MBE topic frequency. I can't say enough wonderful things about Joe Seperac, bless his little heart, I passed the bar because of him.
TL;DR: spend the money for Seperac, it's totally worth it
