I imagine, if I keep the momentum going, that I would possibly attempt Developer Test 1 sometime this weekend.   [using some Christmas downtime]

Is there any negative to going for it?   If I'm too aggressive with my timeline and foul it up, can I take the test again?   Any negatives to attempting the test?

Hi Frank,

Go for it, I'm sure you'll pass them in a breeze!
And yes, you can take a test again (maybe with different questions) if you don't master it the first time.

Cheers,
