Online drum lessons HELP page

How do I use the online lessons?
When using the online lesson pages follow the the RED highlighted letters across the top of the page and the same on the pedals show either side in the two bottom corners. The exercises are set at a fairly steady, beginners pace to get you started, I'll be adding more as the weeks go on so any comments on them are greatfully excepted.

What do all the symbols on the page mean?
Starting at the top the row of letters ie: 'RLRRLLRLLR' show the sticking order and in the bottom two corners are symbols that represent the hi-hat pedal (HH) and the bass drum/kick pedal (BD). The animation in the centre of the page represents the snare drum and stick movements.
