I just started my SSI OW Instructor course last week. Going to be lots of work for a while. I took the first of 4 mini- exams & scored a 95% (must get at least a 90%). I also completed a pre- test. That one really kicked my tushie. The physics seemed to be my big problem. Just another obsticle to overcome. Give me 2-3 mos. & we'll see where I end up.
