Hi If u new to the Cattle drive u should start with assignement 1a and work ur way up. U can also start with any one, like i did b4, which is not a good idea but when it comes to submiting them, u have to submit the assign 1a first and when u pass it, the nitpicker will let u work on the 2nd. Each assignment let u learn some stuff the u will use in the next one. Usually the nitpicker response is within 2 days ( for me so far) when u follow the instruscions above. U just can't submit anyone and wait for an answer, u won't get anything back. Good luck !
