My exam does not contain anything that is unique to the 1.2 exam, but it does contain material that is unique to the 1.4 exam. The assertions topic is the most obvious example. The new collections questions in the beta exam section cover the collections that are new to 1.4. My exam is still under construction. For example, it doesn't yet cover garbage collection. My exam is most helpful if you use it like an open-book homework assignment. The score that you get on my exam is not the best indication of what you would get on the real exam. The feedback that I have received suggests that people usually score low when they take my exam for the first time.
