Sorry, that was a really ignorant suggestion I made - never considered that you might actually be using Polish software!
You were right - this letter was better - except for that faculty sentence I could imagine it coming from one of my neighbors.
I don't mind commenting on your practice letters, but if you want feedback from some other readers, maybe you should start a new thread. That might give someone else a chance to give you some opinions. Did you say you planned to take the exam soon?
