+ Working Overtime
+
+
+ You and your project partner are deciding whether to work overtime based on your remaining workload. The parameter ``yourWorkload`` represents how much work you have left, and ``partnerWorkload`` represents how much work your project partner has left, both in the range from 0 to 20. The result is an ``int`` value indicating whether you both should work overtime. Return:
+ * If either workload is 5 or less (i.e., there's little work left), return 0 (no need to work overtime);
+ * With the exception that if eithr workload is 18 or more, return 2 (i.e., a large amount of work to complete);
+ * Otherwise, return 1 (maybe).

+More Practice (Experiment)
+===========================
+
+Thank you for taking part in this study! We are researchers who are trying to improve the teaching and learning of programming.
+
+*If your teacher is asking you to do this experiment, please wait until your teacher instructs you to complete a section. Do not start it on your own.*
+
+This study has three parts. It will take approximately 45 minutes in total to complete the study.
+Please do the parts in order following your teacher's instruction, and answer questions to the best of your ability without any outside help, and please do not discuss with others. You can stop working on a problem after you worked on it for about five minutes without solving it.
+If you have questions about this study please email Dr. Barbara Ericson at barbarer@umich.edu.
+
+The three parts are:
+
+* 1. Pre Test - Questions that measure your knowledge prior to doing the practice problems.
+
+* 2. Practice - Practice problems. You are going to be randomly assigned to one condition. After you open this page, please finish all problems in one session, otherwise you might lose your progress.
+
+* 3. Post Test - Post test problems that measure your knowledge after doing the practice problems.
+
+Based on your teacher's plan, you might do all three parts in one class, or do part 1 at the end of one class and part 2 & 3 at the beginning of the next class.
