Wearing my old OTIII-sup hat for a moment, and remembering some discussions on a FZ board ten years ago, I would guess that he's going to run into trouble and not find many, if any. The OTIII C/S (they don't bother with sups, unless that's changed) may do a correction list, then when that doesn't do much, will tell him he can attest as "obviously his NOTS case need handling" or some such out-tech (per Hubbard's tech) bullshit.
Did he "do" OTII? Did he get very far?
Send me the OTII/OTIII worksheets that the "C/S" has C/S'd and I'll (privately!) critique it, if you like, and point out all the (per Hubbard's tech) gross errors. Heh.
I have recently acquired the advanced ability to do C/Sing by remote.
Right this moment, I am "pervading" those OT III worksheets and can state with certainty that every single page, from top to bottom, is filled with Gross Auditing Errors (GAEs).
In fact there is nothing in those worksheets that is
not a GAE!
REASON: Amongst many others, one of the primary GAEs is breaking the AUDITOR'S CODE--in which there is definitive scripture which prohibits INVALIDATION and EVALUATION.
Since the ludicrous children's fairy tale known as "Xenu and the Volcanos" is all simply a revenue generating Ghost Story to scare adults into yet another one of Hubbard's "Make More Money" ruses, the entire level is nothing but invalidation & evaluation:
INVALIDATION: Hubbard's "r-factor" (as Founder, researcher, originator of the tech and "senior C/S") to every Pre-OT is that they are a degraded being, because they are packed with other degraded beings. And because they are loaded up with DBs, they (themselves) have been "degraded" not just recently, but for 75 million years. Furthermore, Hubbard "briefs" every OT III student/pc with the "scientific data" that they should have many supernatural abilities (e.g. exteriorization, levitation, postulates...) but that they are so degraded (by reason of body thetans) that they are no longer able to function as an omniscient, omnipotent "Operating Thetan". Thus, on top of directly telling the Scientologists (that are paying Hubbard hundreds of thousands of dollars) that they are degraded beings, he hammers out of existence any slightest self-confidence, self-esteem or self-worth they might have--turning them into helplessly pathetic "humans" who cannot survive without paying for Scientology's advanced levels.
EVALUATION: Hubbard evaluates for every single PC on the earth and instructs them (under threat & penalty of increased tech estimates, ethics or declare) that their past lives were all the same. That they all had the identical "engram" at the hands of Xenu. And that they all are in their present Homo Sapiens condition (an eternally perilous & horrific state, according to mankind's greatest friend) due to Xenu's "implants", consisting of "false ideas" (i.e. any idea that is not sold by Hubbard) and the assassination of the world's major religions (e.g. implanted pictures of Christ, and other chief competitors to Hubbard's Scientology religion brand).
SCIENTOLOGY GLOSSARY:
OT 3: -noun: 1. The third Advanced Level after a being attains the state of Clear. 2. OT 3 ("Old Trick Number 3") The 3rd trick Hubbard employed after Old Trick #1 failed to Clear people in 1950 and 1951 by running their "engrams"; and, after Old Trick #2 similarly failed to create an Operating Thetan with all the materials developed and tried from 1952 to 1967.
