Hi,
Not sure who you're doing your learing through, but I'm over 1/2 way through Module 1 with BGS.. The work load is hard and there seems when you start a Hell of alot to get through, I think the progress test are just there to test you have actually read the information, and I know BGS require you to submit all of them before your refresher course.. I don't believe for one second you will remember all of it, If you look at some of the feed back questions you start to get an idea of what they are looking for in each subject and that way you can tell what is relevant while studying. It shouldn't detract from the fact you need to learn or at least read through the subjects, but more enables you to focus on the key points.
