If you do the German, even part-time for awhile, you will have your degrees and some experience and could get in a Masters program in Education that way.

Another thought; any way you could do your own reading in the "plant" portions of the basic genetics courses and then test out of the actual courses so you could spring into the more interesting ones? Once you get your basic degrees, the world can open up for what can be cross-pollinated :-) and how to shift what you study/careers. Often when you get to higher levels you just have to "know" the basic stuff, they won't slow down for you or help you but will let you enroll and take the other courses. Maybe reading/studying the dull stuff on your own, in your own way would be easier than the traditional way.
