No, it is not.  However, the Student Edition (Trade Edition) can be purchased
for about $30 from MIT Press (call (800)555-1212 to get the number for MIT
Press; I don't have it handy).

I have found that MacScheme is an order of magnitude faster than any of the
public domain Scheme interpreters which run on the Mac.  For $30, you are
getting a great deal.

A minor limitation of the Trade Edition is that you are limited to 1MB 
for your address space.  If you want or need a larger address space, you
need to buy the regular version (which lists for about $100) or
MacScheme+Toolsmith (which lists for $400).
