I love KSP a lot. Also, this year I must enter one of inter-faculty courses in my University and when I've found one of them is "Space flights: operative control of spacecrafts" I understood THAT is the one as it is KSP IRL. Somehow I also decided to give away three copies of it in case someone else will find it helpful... somewhat... I guess...
So the giveaway ends at the start of the first lesson.
Winners will be added to send gifts to them.
