The password is left to the examiner to generate. I found the best method was to use the random number generator on my calculator. Other methods can be used - for example the student's computer registration number. Passwords offer some level of security to exist within the system. For security reasons I found it best to allocate each password to the respective student as they entered the computer lab prior to taking the exam.
Passwords also exist within the gradebook, but are hidden from general view.
The examiner is able access these passwords. Once the gradebook is set up, it can be easily saved to disk. The gradebook permits more than one exam to be entered, and each exam can have a different weighting level if required. Test level i.e. aggregated analysis of a particular exam Class level i.e. aggregated analysis of how the students have performed on all exams. Thus, the examiner can keep a record of each student's progress and check on each individual performance.
