Discounted Webassign Access Code ($40)

If you have not already purchased a 195 Webassign Access code, you can purchase one for $40 by scrolling to the bottom of this page REDUCED PRICE 195 ACCESS CODE. If you already purchased a 195 Webassign Access code in a previous semester, do NOT purchase another code. Your old 195 Access Code will work this semester. If you already purchased a 190 Webassign Access code last semester, you MUST now purchase a 195 Access Code for $40. Your 190 Access Code will NOT work in math 195.

Your 195 access code remains valid even if you need to take math 195 multiple times. Before you purchase an access code, you should take advantage of the free trial before purchasing in case you need to drop the course.

Quiz and exam questions will be similar to the assigned homework questions. You should attempt all the assigned homework problems to learn the material and prepare for quizzes and exams.

If you are taking multiple courses outside the math dept. that also require a webassign access code, then Cengage Unlimited may save you money? You should then compute what is the best value for your semester. If this is the only class with Webassign you are taking this semester, the cheapest option to purchase an access code that I know is the $40 option in the above link.
