Diagnostic Test Question

I'm not sure that the score that received on my diagnostic is accurate. Does the score that appears take into account only the questions completed within the 35 minute allotment or does it grade the test in its entirety including the questions I continued to work on past the time?(I only continued because it said that it would give me a better indicator of what I should work on). If it is the latter, the score is inflated being that I completed all of the questions regardless of the time.
