Good afternoon Felix
Thanks for posting on the forum with your questions. I see that you have already been savaged by the Grammar and Syntax Nazis! The fact is that a modern British education does not seem to equip people for reading and writing in the world outside school but you have already acknowledged that and accept that you have to work on these.
Another prospective pilot posted here a few days ago and was given a very hard time (IMHO). However, you might like to read thru his questions and and the few relevant and helpful comments that he got. You might find some are applicable to your situation.
Your first posting wasn't 100% by the book but it was way better than his!

Good luck and don't be put off by the 'Banter'
3 errors of grammar, punctuation and syntax in post #4, BTW, not that I care!
