While writing this I am currently sitting at approximately 3 hours. Overall, I think the 6 activities, though occasionally time consuming, were very manageable. I think some of the activities took a bit longer than they should have due to a number of mental oversights I had. Nonetheless, I'm glad the information regarding new activities/procedures (such as the relational databases) seemed to stick in my mind enough to allow me to function with minimal outside help.
I don't know if too much needs to be changed to improve the test further since everything seemed good to ease in a beginner. Being able to look back at the modules (and the explicit instruction to do so) for a quick refresher definitely helped a lot at mitigating stress and effectively carrying out the tasks. I look forward to further training my technical ability and will be sure to refer to this test as a valuable practice resource.
