hi, basicly, you need to know how to do a heelflip and a frontside popshuvit first. you start by popping like you would for a frontside popshuvit, but with your front foot you flick it outwards away from you. this will cause the board to flip. TIP: the board sometimes seems as if its going backwards when you spin it, but normally its just you jumping forwards, so if that's the case try and jumps back a bit with the board.
Here are the ones all new skaters know(I don't mean they can do it but they know what they are) Ollie Kick flip Pop-shuvit Nollie Heel flip Varial flip 360 flip
Yes that should be good enough if you do it down stairs
snick flip
maybe a storm flip=nollie frontside 180 heel late flip. by jerry hsu
laser flip to bs nose blunt out nollie inward heel
well the hardflip does a kickflip and a fs huv it vus making it turn backwards or heel side. the varial flip is a kickflip and bs (or regular) po shov it. vus make it turn forwards or toe side.

they are pretty much grabs boneless, airwalk, tail grab, rocket, mctwist, 720, one foot grab, ollie back flip, toe flip, crooked, heel flip
not neccisaraly. it may take you three months to varial flip. but could take another year to tre-flip...or even heelflip
Im guessing the 900
theres no average tricks for a specific age, i skateboard and im 13 and i can kickflip varial kickflip, big spin, heelflip, pop shove fs bs etc and i have friends that are my age that can nollie double tre flip. so it depends on how much you practice and how naturaly talented you are
if you can do those tricks over a 12 stair, then i guess you are good.
