For the first week of class, you've had lots of current WebAssignments but few of them have come due. You might look at that and say, "There's not much to do."
What you have to keep in mind is what things will look like as the first test is approaching and EVERYTHING seems to be coming due at the same time that you're trying to prepare for the test. What's the thing to do to prevent crunch time where you crash and burn? Very simple. Attack your homework soon after it appears rather than waiting until the last day or so before the due date. There's a reason I give you about 10 days for completing each assignment. That's the reason.
