You should reread the downloads rule. Nowhere does it say your posts need to be related to any one particular subject. You can post about anything. Useful means not posting rubbish in an obvious attempt to reach 5 posts. Most people overlook the fact that you also need 1 "like".
Your very first post should have been in the "Who are you" section. Instead of the usual Hi or Hello crap, a detailed introductory post can often be rewarded with multiple likes even if only for showing some effort.
I got one answer wrong on the 2377 because I misread the question
Your posts above are questions to which you should already have googled the answers to if you are serious about taking the 2377.
I'm not trying to run you down mate, I'm just trying to point out that there is far more to this forum than this section alone.
