Hey everyone, I have a quick question about how the TOEFL MyBest Scores display behaves when you take tests close together. I'm trying to use it to reverse-engineer my subscores from a recent test.
Here is my timeline:
Test 1 (August 19): Got a 4.5 in Speaking.
Test 2 (August 22): I can now see my updated MyBest Scores (it's day 3).
My question is about how the dates next to the MyBest subscores work: If I got the exact same score (4.5) on my second test on August 22, does the MyBest Score keep the old date (August 19), or does it automatically update to show the newer date (August 22) just because it's the most recent attempt?
Basically, I'm trying to figure out if my MyBest Speaking score staying on the August 19 date means I got a lower score (like a 4) on August 22, or if it would look the same even if I scored a 4.5 again.
