Adding DAT(Dental Admission Test) prep

As MCAT is important for premeds DAT is also an important test to get into competitive Dental schools. MCAT does have many preparatory sources but DAT has comparatively less. Pre-dent students like me would find it very helpful if there is a reliable free learning resource for such an important entrance exam. Khan Academy is helping students around the world to get free and most reliable education and I am really enjoying to be one of the students using Khan academy. It is my humble request to add DAT prep to help predental students. Thank you...
