The key to this would be the LSAT coordination office that collects everything you need to apply to law school and then acts as the agent for you when applying to all your choices. They need every record, admission of parking tickets, arrests, every school you ever attended, sealed transcripts, etc...... That is if it really was him who took his own LSAT? Now they fingerprint you to take it. Back then they did not.
I did not know that. LSAT, wow!
