Retaking OAT/Plz Help

Hi everyone, I am so sad because of my bad OAT scores. I am even crying while writing this thread. I had my OAT today and struggled with timing. I was shocked seeing 15 paragraphs instead of 10 for RC, I was also frustrated with QR/Physics section which required a lot of calculations. The easiest one was Chemistry (that has always been my strongest subject). I took bunch of Kaplan practice tests (super hard) and ADA test from 2006 which was very easy.

So I wanted to get help from you guys...
