Hi SANNUS,
You're correct that the GMAT is a question-adaptive exam, and the difficulty of the questions you see adjusts based on how well you're doing.
As you answer questions correctly, the test gives you more challenging ones to better assess your skill level. Regarding your question, purposely answering questions incorrectly will for sure leave you with a lower score, so I do not recommend doing it. The algorithm rewards strong and consistent performance, not attempts to outsmart it.
The best approach across all sections, Quant, Verbal, and Data Insights, is to focus on accuracy and time management rather than trying to manipulate the system. Here is an article with more details about GMAT scoring.
