Where exactly are you stuck on the games? The advice varies in different parts of the game
If you're challenging AAA and you have trouble with the later levels of AotR, here's a tip: if you get to the level where you have to get like 750 to advance was it? Anywayz, that level where things become much too fast: just let the cannons burn down. If you use the cheat to get an extra life (only works on level 3 and later), you have enough lives left to continue playing the level. With the cannons out of the way, you can move in the front row undisturbed again, and you can also concentrate on the boarding pirates as well (no more filling cannons and hosing them down).
This works for just one level, since the cannons will be restored the next level, but it'll be enough to get the required score
If you can't get to this specific level yet, then all I can say is: practise
