What is your opinion about my field tested?

I was arrested for DUI. The Officer asked me to take 10 steps towards her heel to toe and count to 10 (soon as I got to back of my car) I listened when I reached her she asked me to turn around and count to 10 again- other direction. I then had the chance to explain, I’m Disabled and could not pass any test with my disorder". She said okay asked me to stand on one leg (I said "I can't pass that either ") then checked my eyes with a Pen -after another officer arrived then he took me for blood work. In the police report she stated I failed the heel to toe test and the one leg test no mention of pen test .Can the charges be dismissed on these facts alone false police report or incomplete to be honest I could not say if I passed the 10 steps forward or not. But I didn't miss a number or a step- as I recall. I Didn't Attempt one leg stand. Since it’s my 1st offense everyone is suggesting plead quilt and take classes.
