If I were you I wouldn't worry so much, you've just started, all the info is coming at you at a pace faster than you can cope with etc etc ... really it is a situation we have all been in. The key to it is first believe you can do it, and second to literally keep telling yourself that and actually do it.
If you start now with the questions, getting familiar with them, knowing exactly what they want, speaking to people who are taking their exams now, asking if there are any differences (but do beware of some who will exaggerate the difficulty of their exam to make it sound like they were extra good to have passed it) and constantly working to it you'll be fine. You aren't the first and you won't be the last ... just use the resources wisely
