Ways of remembering quark structure of mesons?

Well mesons are one normal and one antiquark, and with Pions and Kaons (+ versions) the normal particle is the up quark in both cases. So that's a help, and then the -ones are just the reverse. If you only need to know those two then just remember that pions are up-antidown and kaons are up-antistrange. Frankly, because the spelling of Kaon is strange.

I can't remember the structure of the 0 versions at the moment, but do you need to remember those is your exam anyway?

Just remember how to work them out, Kaons contain strange quarks, Pions don't and you can work it out from there as they will both have a baryon number of 0.

I just remember them as Pions = DSU (which is all the antiquarks) and Kaons = SDSU (again all the antiquarks)
I know the pairs it was just remembering which are antiquarks and which are quarks for me!
