YES, the academic update saved me.
My stats, 3.3GPA with a nice upward trend and 23AA/26PAT. Applied in June to 19 schools. ZERO interviews until December after I completed the academic update. Soon after, 5 interviews came in succession. Schools confirmed that the academic update helped me.
My problem? I still needed to complete some prereqs but didn't anything down for planned coursework, even though I was still taking classes. BIG MISTAKE. I live in Ann Arbor, and this is the reason why Michigan insta-rejected me. I live down the block and they flat out rejected me. I was so demoralized when I saw that..
Anyways, yup... academic update saved me this cycle
