In this project, I created a step based intelligent GRE tutor. The tutor focused on fill-in-the-blank vocabulary questions. The tutor first asks a user for their own word for the blank, then uses Wordnet to determine if their answer is reasonably close to the correct answer. Then it asks the user to evaluate each answer choice in relation to their own word. Finally, they select an answer. This three step approach teaches students a useful technique for being successful on the GRE and improves student vocabulary.
