Well I just failed my 2nd attempt of Checkpoint 3. I got 4 questions incorrect and though I'm confident I can get at least 3 of those correct on my last try I'm somewhat perplexed. For a start, it's the first time I've failed a checkpoint even once, let alone being on my last try and secondly as far as I was aware 75% was what was required to pass the checkpoints/assignments. (33/37 = 89%)
Not so much asking for help on those questions as I think if I sit down long enough I can cover it, however if I fail the course based on getting one question out of 37 incorrect I won't be best pleased so just wanted to check beforehand what's the deal with that?
