My university teaches the Andrew Keller Series of textbooks in three semesters. It used to be two ,but they felt that was too fast. So, I went through the program of those books ,and it covers the basics. Then you can pick up Smythe and learn all of the exceptions. So, I got to that level in about a year given a semester is 4 months. Fourth semester Greek is simple reading as you describe.
Smyth smites all others
