Yes, DSST has a practice exam of about 10 questions and an Idea of what the essay is like. Using both DSST book and instantcert is a great help. I got a 73 and used both. The exam is largely based on Yes/No answers based upon situations. I sometimes think the exam had little to do with what I studied and more to do with answering yes or no based upon the concepts I learned. You should do fine using both study materials.
