Pluspunten
Good hours and pay rate for a part time or supplemental gig. Really easy once you memorize the material, and they're always trying to get you to learn new tests. The training is compensated.
Minpunten
The corporate structure is a little oppressive: having to navigate the bureaucracy as well as represent the myriad interests. For instance, placing the onus of explaining the various guarantees and money-back claims on the tutor is a bit ridiculous. Also, the offers for gigs come at the last minute, with almost no time to prepare. And in the case of NYC's market, the jobs are often far off the beaten path and mileage reimbursement is only paid for trips over a certain amount of miles...so you are often asked to travel two to three hours roundtrip for a two hour job.
