CSUF Students should complete all four tasks in the order listed, keeping a record to make sure none has been skipped. To get full credit, you must complete all of the parts listed below and spend at least 30 min. on the tasks. Please read the instructions carefully, as no credit will be assigned for random button pushing or other failures to follow instructions. Please do all parts in one sitting, without distractions or interruptions. There is no incentive to rush because if you finish early, you are required to continue on page two until you have completed 30 min. of tasks for the 30 min. credit.
