Will my score be considered valid or not?

I want to know if my score is considered valid. I took a pattern recognition test. First, I did the 35-minute one, but at minute 15 I paused for 1 minute to drink water because I felt thirsty. During that pause I did not review or think about the questions—in fact, I left the page and just went to get water. Also, I didn’t really rest; throughout the test I felt tense because it was timed. When I came back, I resumed the timer exactly where it was and my answers stayed the same (they were saved since I only minimized the page). When I finished, I had scored 6/20, which corresponds to 129.5.

But I noticed a very silly mistake that I probably wouldn’t have made if I hadn’t been so tense. The error was something like counting letters: for example, I should have written how many of each there were, but due to tension I wrote 44561 instead of 44562. Another example: if the sequence was something like “xzzijojooe,” the correct answer would be 121231, but because I was tense and distracted, I wrote 12130. It wasn’t because I didn’t know, but because I didn’t notice. So without that mistake, my score would have been 7/20. I had another similar mistake, but I don’t count that one because it was also due to not noticing.

So without that error my score would have been 134. I don’t know which one to consider, 129 or 134.

Then I did the second part of the test, which was 1 hour and more difficult (20 questions). Again, at minute 20 I paused for 1 minute because there was a lot of noise and distraction in my environment, and I couldn’t concentrate. I paused the timer and didn’t think about any questions. Then at minute 26 I had to pause again because I had to leave urgently, and I was gone for about 15 minutes. During that time I didn’t think about any questions or answers—in fact, it made me even more tense, and I didn’t remember anything when I came back. I resumed the timer and had 14 minutes left. I didn’t change any answers.

At the end, I scored 7/20, which corresponds to 138. The tests were numerical HRTs with letters, so during the pauses I didn’t remember anything because the numbers were very long.

My concern is whether my score is considered valid or not.
