No offense to the HG, but if you want an EA, grades will matter more than being the HG CC because HG is an EC, just like Arnie, silver or Angel.
~~ Grades and your major + rated or not rated.
FWIW, the fact that you are the CC for HG = peer respect and I would bet you have a PMS officer as a guidance/adviser. That means to me you already received points/respect to make it to HG CC as a 200 from your det.
