Do whatever it is you need to do to get back on your feet. You have a little over two months until the September test. You haven't failed completely if you can just get back on your feet quickly and try again. You know where you messed up along the way..don't spend time thinking about what went wrong outside of the question types you messed up or your strategy. It's not going to be easy, but nothing worth having is! Get on your grind.
