Yeah, it's true... The monsters and the bosses level up in conjunction with your characters levels. In my opinion, using that no level up strategy really isn't the best way to play FFVIII, especially if it's your first time playing it fully through.
The truth is, there's always someone out there with a special strategy for circumventing the (Battle/Junction) system making the bosses and final boss a piece of cake to defeat, and if your experienced with the Junction system, that may be the case. However, the final boss can be both easy and impossible to beat at any level. Again, it really all depends on how well you learned the (Battle/Junction) system and the strategy that you'll end up using in the final encounter.
The best advice I could give, would be learning and using the battle system as the original developers had intended it to be used. Level up the way the game had intended you to. ALWAYS, always check monsters and bosses to see what you can draw from them, more importantly, don't circumvent the battle system with someone's guide on the net, you'll likely cheat yourself of a valuable magic or item with an intended use for later on. Like I said, if needed get a good (normal) guide on the net and play the battle system the way it was intended to be played. Trust me, it truly makes the game far more enjoyable, in my opinion.
Lol... Sorry for all the rambling above, but as you can tell it's my all-time favorite FF's. It's a great game and it has one the best endings, in my opinion. With that said, I really do hope you enjoy it this time around.
