That's right, but I doubt you can eliminate your mistakes entirely. I have done about 3000 questions and now I always make ~7-10% of silly mistakes and face ~3-5% questions which I don't understand and/or I completely don't know the answer. However, practicing is very good way to reach ~85%, but there always be ~10% silly mistakes, which you think you shouldn't have done but you always do them.
