Pros
Class assignments are available on a per-term basis (for a specific LSAT administration) and last about two months. There is a lot of flexibility regarding how much and how often you teach. For example, you could come in and teach just during a summer or work for years teaching part-time throughout the year. Classes are generally in the evenings, so the job pairs really well with schoolwork or another job. Their "rover program" is particularly cool: they relocate you for a term to an area where they need an LSAT teacher. In addition to the standard pay for teaching classes, tutoring, and helping students online, your housing is entirely paid for. Great way to earn a bunch of money in a short time. Some people rove for just one term, and others have been doing it for years. The company provides extensive training both before you teach your first class and ongoing support after you start teaching. The administrative staff in California is super helpful and nice.
Cons
Can't think of any. Just keep doing what you are doing!
