[plt-scheme] where to begin

Two sites that have interesting programming exercises
are the following:

Project Euler: http://projecteuler.net/

Rosetta Code:
Solutions by programming task: 

Of the above two, I would first recommend Project
Euler because of the following reasons:

* Each problem is stated succinctly.

* It offers a list of problems listed in progressive
order of difficulty.

* Each problem has been designed according to the
"one-minute rule," "which means that although it may
take several hours to design a successful algorithm
with more difficult problems, an efficient
implementation will allow a solution to be obtained on
a modestly powered computer in less than one minute"
(courtesy of

* For registered users, the site keeps track of the
number of users who have solved each problem.

Useful programming references for these exercises
would probably be the following (in addition to the
PLAI book
already mentioned in another post):

How to Design Programs (a.k.a. "HtDP"):

Concrete Abstractions:

You may also wish to consult the following reference
for language-specific questions on the Scheme
programming language (as opposed to questions on
programming in general):
Teach Yourself Scheme in Fixnum Days:

Eventually, once you are up to the challenge, you may
wish to try the following classic as well:

Structure and Interpretation of Computer Programs:

There is another interesting programming challenge I
discovered recently as well, but because I myself am
currently working on this project, please let me solve
it first before I post it here.
