Don't worry about your ratings. I had the same issues as you when I first started. I took pride in that my rating was 4.9 or higher for the first 150 trips. But then the law of averages started to eat away at my ratings and nerves. It drop in three weeks from 4.93 to 4.85. The worst part was I could not find any reason I was given low scores for those three weeks. I went over and over on each trip but could not justify any reason for the low ratings. Now fast forward to the present. Over 950 rides and a 4.88 rating. If you are providing great service in a professional and timely manner everything will work itself out. Also dont worry about those annoying emails threatened to diactivate you for high cancellations or not accepting request. We all get them and unless you are abusing the system you will be fine. I also starting today to drive full time to see how much money I can earn. My goal is $500 . Good luck on the New Year!
