Am I good to go?

I recently took a HFT with psychemedics. The company sent me an email 2 business days later saying I successfully satisfied all requirements and gave me info to finish my hiring paperwork. The stress is killing me and I need to know whether I passed or not because I have another offer on the line and a current job. Both start dates are the 8/12 so i need to let the other company know soon that I will not be working for them and let my current employer know.
