Throwing in my 2 cents here, and as SEHQ said, yes, you will see 7-10 on the morning portion both days. The practice exam/book put out by NCEES has 8 questions in the morning on both vertical and lateral.
Now when it comes to the AASHTO, you don't need to know it backwards and forwards. You DO need to know how to develop loads on the bridge (both vert and lateral) and be familiar with where the chapters are and how they are laid out. You can easily get 75% of the bridge questions right with just what I've said above. When I took the exam last April (2014), I could develop the period and loads for seismic quickly which helped me on the lateral portion and I knew what load factors and combinations to use by looking at that table in chapter 3. (I forgot which table it was, but I know it's in 3. This is a good example of how well you should know the AASHTO.)
Also, as with everything else on this exam, if you use good engineering judgement and knowledge you can usually tell if you're at least in the right ballpark for your answers.
