<p>How important is it to familiarize yourself with the case study before the test? Will all the information that you need to answer the case study questions be included in the reference sheet? Thanks</p>
<p>you should definitely read through it once, but don’t stress over little details. Think of the case study as one big example covering everything the rest of the course teaches.</p>
<p>you need to have an idea of the relationship between the classes, but you don’t need to know every method and which class / interface it belongs to. however, it doesn’t hurt to know some of the more important ones and frequently used ones. the AP exam guarantees that 5 MC and 1 FR will be based on the case study, so that’s a good chunk of your grade. you should know it</p>
