Math 20B Homework

Updated 4/17/19

There are two types of homework in this course: online homework (which will be graded) and pen-and-paper homework (which will not).

Online Homework

Online homework will be done using WebAssign. WebAssign can be accessed from within TritonEd under "Tools".
If you enrolled after the first day of classes, it might take a day or two before you make it into the system.

Access Codes:  To get an access code for WebAssign, you can either (1) purchase the textbook from the UCSD Bookstore, which comes bundled with a multi-term WebAssign access code, or (2) purchase ELECTRONIC ONLY access from the WebAssign website (after first logging in through TritonEd). If you already have a multi-term access code (because you took Math 20A last quarter, for example) then you may use the same code. If it does not work automatically, you may need to contact Customer Support.

Logging In:  Log into WebAssign from TritonEd. Select "Access WebAssign" either directly from the course menu or by first selecting "Tools". The first time you access WebAssign for this class, you will be asked to login to a Cengage account if you have one, or to create a Cengage account if you do not already have one. (Cengage is the company that owns WebAssign.) Normally, you will only have to log into your Cengage account the first time you access WebAssign for a course. (If you take another class using WebAssign, you should link it to the same Cengage account.)

For subsequent logins, you can either login to TritonEd and select "Access WebAssign", or you can login with your Cengage account at www.webassign.net. The top right corner of the WebAssign screen should show your account as "Welcome, username::app-173@ucsd" rather than "username@ucsd.edu". When you logout of WebAssign, it goes to WebAssign's direct login screen, instead of bringing you back to TritonEd. Just close the window.

Trouble Logging In:  If you have trouble logging into WebAssign, contact WebAssign Student Support.

Due Dates:  Online homework due dates are subject to change based on variations in course schedule or technological issues, but will generally by due a week after being assigned. All online homework assignments are due at 11:00 P.M., unless specified otherwise.

Late Submissions:  If you need to turn in some of the homework problems late, it is possible to request an automatic 4 day extension of the due date. Extension requests are only valid until 2 days after the original deadline. Late submissions earn a maximum of 50% of their total score. (This penalty applies only to exercises submitted after the due date and not to those already submitted before the due date.)

Attempts:  You are allowed 100 attempts to answer each problem except multiple choice problems.You are allowed one attempt on a multiple choice questions with two or three options, and two attempts for those with four or more options.
