Hey sorry to hear you are failing 133. For me I thought I was failing 133 until the final grades came out lol. There is still a chance when you are studying for the written final. Make sure you understand everything that she talked about in the final review. It WILL come up in the final. She does a very good job of being clear about what kinds of problem will be on it.

To study for the final make sure you do each of the problems 3 times with different inputs. like if you are finding the subnet of the network, do the problem with 3 different IP addresses. I feel like that had helped me.

It isn't really over until it's over! You still have a chance. do your best and then let the curve help you pass! Good luck!!
