I am taking arabic ab initio!
Its really easy, all the past papers are the same. We personally take things about transportation, how to right letters to a friends or an email, we talk about food.
The traditional ab initio exam is about 4 or 5 topics about certain subjects they choose. You read it, and questions follow it. They are direct questions, no need to study for anything. I dont remember the last time I studied, and i get an A+ average. My predicted is a 7 and if there was higher, i will get that too.
After doing the stories, which look like case studies, you have to write. Thats when the stuff you learned in class come in. You MUST know how to write a letter to a friend. They will ask you to write a letter to a friend telling him/her about your arabic language course, for instance, or about a trip you took, etc........
Its easy, don't panic. If you need anything, just PM me and I will be more than glad to help you!!
