o Most weeks, problems assigned Wed and due next Wed. o You have 4 tries to submit each part of a problem on WebAssign. Only the last submitted answer is graded. o You do not have to do all problems at the same time. You may work together, but each person must submit their own work. Most problems have randomized numerical values that are different for each student. Be careful with units. WebAssign chooses the units for the answer, so make sure that your numerical answer is in the correct units indicated by WebAssign.
