to Vilios:
I have had the same problem. The mixed test with "abc x katakana x hiragana" is damn good for practicing, but it is a quite difficult test at the begining. I started as an absolute beginner... so I try to write down everything what was helpful to me:
1) Have you already tried "Katakana song" and "Hiragana song" by genki.japan.net? Check their youtube channel called "GenkiJapanNet" - their educational videos are very easy to remember (especially the one with counting /rapping/ the numbers).
2) The best way how to remember it - I found a very simple way: you must use it. The most important thing is writing, I think. I helps me to be more familiar with the symbols. It is a much more effective way than just looking at them.

I recommend you to go this way: JCJP -> Start learning -> Grammar -> Tae Kim's Guide to Japanese Grammar - > Japanese Grammar: the chapter about Hiragana (and Katakana)
There are the very useful tips and notes in this section. In the hiragana section is mentioned the poem "Iroha" - see:
http://en.wikipedia.org/wiki/Iroha
There is showed the stike order in these sections too and moreover you can get your pdf practise sheets here.
Learn one line of the table ( or two) -> try to draw it into the printed pdfs (To be honest, my first hiragana symbols looks like the supreme collection of the chicken hens. BUT it is a damn effective way, really! ) -> then go back to JCJP´s place and do practise in the Hiragana/Katakana practising to gain exps.
