Received a PM asking me to reply.

It depends on several variables, but leaving questions blank definitely hurt your score significantly. For 1 question, the penalty can be anywhere from zero (if it was experimental) to about 5 percentile points. For 3 questions, the penalty was probably around 8 to 12 percentile points.

The penalty probably was not limited to just those blank questions. I assume you realized you were running out of time at some point earlier in the section, and you started rushing and making guesses. If you had strings of questions wrong at the end of either section (or both), then that would lower your score even more. Can you describe what happened with your timing in more detail?

Take a look at this article for more things to think about (and, if you want to discuss, do the analysis described in the article, and then add that information to your post here).
