Therapist Development Center was spoken of highly at my place of employment. I figured, if that many colleagues have passed this exam using this program, they must be doing something right. Purchased by access, and got to studying. The rationales were great, the test banks were amazing, and the study material just made sense. Now, a day after PASSING my test :-) - I can really attest to how prepared I was. The last two mock exams are spot on. I scored well, and I approached the test as confident as ever. It all showed in my passing score. I would recommend this program, and I will be utilizing it to study for the clinical portion!
