Yes, it's perfectly normal. You could easily make many mistakes and still get a great score.

Next step is to maintain momentum. Keep practicing and find out why those 14 questions were wrong - review the concepts where you had trouble.
Thank you Karishma!
At the begining, when I saw those 14 questions that I failed, I felt depressed.
But surprised when I noticed that my score was 49 in Quant.
My doubt now is when I should stop. When I could say: Ok, it's enough. I am ready. I would be fine with a 49 because I think that a 50 won't increase my overall score, right?
In this sense, when could I say that I am ready for a 49?
PS. I expect a 40-42 in Verbal.
