This course is for pre-dental students preparing for the Dental Admissions Test (DAT). Most students find the Perceptual Ability Test on the DAT the most difficult, specifically the Top Front End (TFE) section. I've created a step by step tutorial that can prepare ANYONE to become a pro at the Top Front End.
This program is designed to teach you various concepts and approaches as the problems gradually become more advanced. There are expensive programs out there with interactive 3D models and color coded explanations, but there are many students who still are lost because they lack the foundation for this subject. What you are getting is the knowledge you need that isn't taught with a model. Learning the way to approach problems and knowing what to look for will help shorten the learning curve on this difficult topic and save you more time during your studies. Your time is valuable, don't waste it learning the hard way.
With all the stress and time that is put into preparing for the DAT, my goal is save you that precious time learning this section and make it less overwhelming. Lastly, and most importantly, help you understand the topic more effectively
Good Luck!
