You are awesome man!. I wish I would have all this stuff when I was a school going kid.
I had a phobia for learning in front of the teacher and had to say yes even if I don't understand what the teacher is saying.
When I was in the school I even disliked the way some of the teachers were teaching which was one of the reason for me not performing well in those subjects.
