PCCC has a requirement that, before you graduate, you successfully pass the College Writing Exam, or CWE (formerly GWE). I am about to mention this in my classes, so I wanted to type up what I am going to say here to share.
First of all, you don't need to wait until your last semester. As a matter of fact, it is advisable that you do not. Why? If you do not pass the CWE, you don't graduate. You will notice it is listed as a requirement on your degree audit.
Secondly, they give you two hours. Many students assume that two hours is there in case they need it, but the expectation is that you are using that time not only to write, but also to plan and revise your work! There is no harm in taking 15 minutes to outline, then writing, and then re-reading it and editing, and since you can take it on the computer, you can cut and paste bits and pieces, delete, etc.
The school has set up some free CWE preparation workshops that are free, and you can find information on them here:
