You have to give yourself a big pat on your shoulder for a job well done, ha, ha, ha!!!
Well, brace up because you are in for a big surprise!!! GT F#2 is difficult, most especially, the "Intervals" tutorial!!! Whoaa, I did not get it and will return to that section. Instructor C.Schlegel is very good but the problem is myself! Just can't get them into my brain!!!!
Good luck!!!
