What's the fastest way to beat hard levels? (preferably without boosters)

 It feels like a waste of time trying to play the hard level every time - so how many levels should I skip before the game will let me beat it?

ugh typed this wrong and can't edit this (I asked this question last night, feeling tired) - I meant how many times should I quit the hard level until it will let me complete it... since the game's guaranteed to make me lose anyway -_-
