My 1st Performance Dashboard, 62% tasks qualfified, too horrible?

Hi there ! I have been working for a month. I thought I was doing a good job. I only had knowledge of being disqualified in one type of task But now I've received my dashboard and I have 10 qualified and 6 unqualified : 62%

I understand this is a horrible performance. I thought I was doing Good. Is this too bad? Is it normal? For someone who's just started.. any advice?? Thank you
