Is there a good way to remember strong acids?

This is for Chemistry I, so there are only six that I need to memorize right now: HClO4, H2SO4, HI, HBr, HCl, HNO3. What is the best way to remember these? I don't need to know what the formulas stand for; I already know that. I only need a good way to remember that these are the strong acids that Chemistry I students use. Thanks!
