Okay, guys, after months of training for it I finally went to my instructor certification (Phase A)& I found out I passed! It was the hardest week of my life, my friend who came with me ended up in the hospital for 5 days due to over-enthusiastic leg kicks from his partner.
The two things that worked most heavily in my favor were 1- my instructors at home are a bunch of demanding, merciless, nit-picking slavedrivers. And 2- I'm used to training/sparring with guys, so my female partner at Phase wasn't able to hit me as hard as my usual partners, even when she was giving me her worst. I've already started teaching my own classes & its going really well.
Thanks to you guys for all your great advice & support.
