MBA Consultants and Bad Transcript Questions?

First off, are MBA consultants worth a damn? If so, how would I find a good one?

Second, I attempted to get a Master's in Engineering without a STEM background, and they let me in for some reason. (My quant GRE was 165, but that was only 67% that test) I vastly underestimated how far behind I was on math. I got a 2.0 my fist semester, a 1.0, my second semester, and failed out. I got readmitted, but dropped out before drop day because my grades weren't enough better. So I have a 1.5 GPA transcript. Applications say to send in all transcripts, regardless of whether you finished school. I sent that to the MBA program (which I should have done in the first place) at the school I failed out of since I assumed they knew about it regardless and got rejected. Should I just pretend it didn't happen for other schools?
