delmoneyy - Thank you for the query.
First, I can assure you that the
GMAT Club Test Center has a near perfect algorithm to deduce the sectional score. That said, I believe your understanding of the GMAT scoring algorithm is not correct. For instance, three consecutive mistake will plummet your score further than if have the incorrect questions separated. Also, a 500-level incorrect answer will lower your score more than a 700-level will do. In your case, did you notice you got 10 500-level questions in the first test and 12 500-level questions in the second test. Well, this data points tells us that you got more 500-level questions incorrect early on in the second test and hence you points were stuck in that level for a longer duration. You had fewer questions to recover the score, thereby scoring only Q42.
Recommendations:
1. Avoid string of incorrect questions. A string of 3 or more incorrect questions is a big NO.
2. Avoid committing mistakes in the 500 level.
3. Be careful about the first 8-10 questions. No 500 level question should be incorrect early on in the test.
4. Do not take more than 3 min for any question at any level.
5. Avoid rushing through the last 5 questions. Target to finish strong.
6. Have faith in
GMAT Club Test Center. Practice diligently and review each test after completion.
