Please do not pile on another letter to them. You already overdid it. As said above,you should not have sent one from your mother, I actually doubt if it will be read, perhaps just in case. Or a freshman teacher, that was a misstep jr teacher or soph at least. The EMT letter yes that should have been the third and final. And it looks like you piled on a lot of extra essay too. Have you not heard ‘the thicker the file the thicker the student?’
These threads are so painful, but I won’t say you are delusional. just a bit if you think many ppl are walking around with such low test scores. But your EMT Study is excellent, the other EC just ok but the one thing is a big commitment. I wouldn’t have recommended you apply. Energy would be better directed elsewhere. I am not sure about the low income tip in a family owned business. There are assets there perhaps and certainly write offs that get added back to income. Maybe so, though.
If you have med school aspirations then you should not be happy to study where you are the bottom 1 pct student. That is not a happy combo. I hope you have your more likely schools in The pipeline. If not get cracking and put some into Meets needs schools asap January 15 is the next big deadline. Seriously assume a rejection and make sure you have options, cheap affordable options are all you need.
