I researched your situation a little bit and here are a couple of suggestions:
1. Get an answering machine or voicemail so you will know when your instructor or Ron Lewis calls you. I know for a fact that your instructor called you at least twice today (he's standing right here and just told me so) and many times over the last few days. Ron has also called you at least once.
2. Be a little proactive and call Ron, the Instrument group, or better yet, your instructor. He's healty now and has been for the last few days.
3. Go to your assigned groundschool which you have apparently missed for the last week or so. You will need to talk to somebody you can back into the proper class in groundschool since you have not gone for a while.
4. Take the help that is offered to you, such as when I told you when I was going to be at school in my PM to you. I also gave you my phone number as I recall and I have yet to get a call. I am flight supervisor all evening tonight if you want to call me or come by.
5. I understand you are around town, as your roomate told me as much, so really, perhaps the ball was dropped by DCA in the beginning, but help yourself and contact us so you can get back flying.
