With the tournament on the 3rd of next month, we're getting into the vicinity. Now's a good time to check your weight and see how you're doing. There will only be a limited window of time when you can email the IBJJF and get your category changed. After the end of the month, you're stuck. So now is the time to start thinking about where you're signed up for and where you will be on the third.
I start checking frequently now so I don't get surprised the day of. Remember, it's not set up like the NAGA, you have to weigh in and walk on the mat. Don't try to cut so much you're miserable the day of.
