Just got a DWI for first offence ever. What to do?

So I live in Minnesota and 3 months ago I had gotten a DWI. Me and my buddy were at the club and I started to drive home and was to tired so he took the wheel. Well long story short, he went into the ditch since it was snowing out. I then took the wheel since it was my car and I felt responsible for it and a cop ended up pulling over and I got hit with a DWI. Now he took me to the station and I was there for maybe 3-4hrs and I took a breathalyzer and a urine test. I have no idea what my BAC was. So after all that he comes and hands me my license and cell phone and says I just need to find a sober ride home. Well now 3 months I received my papers in the mail staing my license is revoked for 180days, I have a 680$ reinstatement fee, I have to pass the DWI/Drug written test, and apply for a new license. Now Im just wondering what I should do? or whats the best option? They did not schedule me a court date so I am not so sure on what to do?
