I think PTC is included in the first Superprep Book, along with PTA and PTB, and PTC2 is the one "new" PrepTest included in SuperPrepII (the other two are previously disclosed, I believe 62 and 65)
@"Sean Siriphan" there was also a paper of corrected typos that came with my book, I posted it here: https://7sage.com/discussion/#/discussion/7611/errors-in-the-official-lsat-superprep-ii
You must have gotten the waiver last year or earlier because I also have the first superprep and I recently resubmitted a waiver application because mine expired and the newer waiver offers SuperprepII
