So my test is about a month away. up to 3 days ago i felt very comfortable with everything. and today I couldn't answer the simplest questions !!!! I took the 2009 ADA exam timed and I completely blanked. I made tons of silly mistakes and couldn't solve simple math and chem questions. Did this ever happened to any of you? if so what to do. I know I still have plenty of time till my test but i'm seriously thinking about pushing the test another month or so. Any advice is highly appreciated.
