I can only help I guess as far as I went and in my journey, I don’t think I really managed to improve all that much in the last few weeks. Again I’ve reached a point where I didn’t want to learn anything new and started basically being fed up with The test instead I focused more on careless mistakes and devising strategies to make sure I don’t lose points on stupid things. This is kind of a personal thing because I’m sure my list of stupid things will be different from yours but I noticed for example that I would sometimes carryover information from one question to another or sometimes reverse weekend with strengthen or have a computational error
So the last few weeks, rather than working on content, I was more focused on execution I guess. Not even test strategy per se, just polishing the execution
however, I would say it is important not to ignore any area even if it’s an area of strengths, still give it a time of day to keep it strong because GMAT is a perishable skill and if you don’t exercise your gmat muscles, your score will degrade
