I recently submitted my initial MMC application and sea service docs and I’m currently self-studying for both the QMED and DDE 4000 exams which I plan on taking early next year. I’ve already purchased the Mariner Advancement USB key and I’m about 80% through the full question bank. Of course I want to study the theory and not just memorize the question bank so I was curious what others have used to supplement the various question banks out there like hawespipe, seasources, mariner advancement etc. What have you guys used?
I’ve seen a few other threads where guys said they used the Marine Engineering Workbook set from Mass Maritime Academy but I’m worried is just going to be the same question bank (plus it hasn’t been updated since 2015). The other option appears to be the “USCG Illustrations Workbooks” by Alan Gillis which were just updated in March 2019.
Before dropping ~200usd on either of these options I wanted to see what people have used. Thanks in advance!
