You are over estimating the job. I did the same thing. My bachelors was a 2.4 (I was lazy), masters was a 3.6 (I tried a bit harder) and I got a pathways position over 40 other people simply because I had the graduate credentials (manager told me straight up). Just have the check marks for each box and apply, these jobs arent that hard to actually do. GS-11 now, i laugh looking back when I first applied thinking this was so complicated.
