Hi Derek,

Starting Fall 2018, the textbooks of all Math Challenge courses should be purchased.  The links to the textbooks, including the print version and the online version, are provided on the class pages of each class on this site.  The only exceptions are those student who registered the courses via the Summer 2018-Spring 2019 Year Packets, who still received the 180-day code of the online version textbooks.

The code for 180-day access of the online textbook is only \$10 each.  Please make sure you get the book in time to do your homework.

Late homework is okay this time; just make sure you turn it in ASAP.
