My team got a 24 but ended up in 4th place which leads me to believe that our build accuracy was pretty good.
The actual mass of the unknown mass was 359.0 grams.
Your test score of 24 was 9th best, your mass score of 28.0 was 6th best, and your time score of 9.25 was 13th best.
Among all teams, the highest test score was 44, the highest mass score was 29.7, and the highest time score was 17.
The first-place team in the event had the second-highest test score, the highest mass score, and the highest time score. Interestingly, this means that the fastest team was also the most accurate.
The second-place team in the event had the highest test score, the 13th-highest mass score, and the 9th-highest time score.
There are two errors in the answer key originally distributed to coaches. The correct answer for Problem 2 is (M-m)g/(M+m), and the correct answer for Problem 15 is 1 second. All exams were graded based on the correct answer key.
If you would like to know your team's raw scores, or if you have any questions about the exam, or if you have any questions about MIT, MIT life, or the MIT admissions process, you may send an email to me at scioly(at)mit(dot)edu. It was great to meet many of you at Yale last weekend (including gneissisnice!), and I had a splendid time supervising the Compound Machines event.
