Helio never tapped, so neither should you! Seriously though, think about formulating a game plan for a few different scenarios. That, or try to improve your weak points and/or your conditioning. What do guys do when they're drilling for competition? I think a basic idea is developing a game plan from a few scenarios, what this does is it takes the active decision making out of the process when you find yourself transitioning. You still need to adapt, but if you've made a good game plan you should more or less be ready for it. You can also just work from bad positions, starting from mount, side control, or back and working your escapes. You don't need to go in I ROLL 100% NOW PRE-COMPETITION, that's for competition. In fact, don't do that with just anyone, do that with a senior member that you can trust, not one of your mat buddies who might get carried away and pop you. Though it is good to have a competition style intensity in your rolling, you can't do it every day, you want to show up on game day fresh. Try not to burn yourself out.
Conditioning may not be as big of an issue for you, conditioning can definitely be an issue if you're for example entering a gi division, no-gi division and an absolute division, which is not necessary for a first tournament whatsoever.
Do you just want to get into and pull guard, or do you want to stop a guard pull and then pull guard yourself, at what I would assume is a lower level you probably don't want to bother thinking about throwing with only 1 month to prepare. Do what in guard passing, do what from side control, etc.
And as other guys have said, remember you grapple for fun, it's not the mundials. Competition does have an extra benefit than this, competition is a reward for your hard work and training up to this point. When you compete it becomes a real-world application.
