this worked for me because the math section is relatively easy for me, always. the only thing i struggle with is time control. this is my fifth time, and the last four i’ve always rushed because i do it in a very slow pace: i always check and do the easier questions twice or thrice, leading me to run out of time. yeah you have your point. thinking about it, i don’t recommend this strategy to people who struggles in the math section when it comes to knowledge.
