I just passed my IFR check ride last week and let me tell you, it was a huge relief to be done with all the studying and prep. Study the acs hard and the oral will be easy provided you know the material. Try to slow down ahead of time if need be for the approaches and hold so you won’t feel rushed. I asked atc for some extra time when they were vectoring me around after the missed approach to set everything up for the next approach and the DPE liked that ( I would do it whether he likes it or not as that’s what I would do in real life). Mainly, don’t go below mda! The check ride was easier than training actually which is the preferred way to go in my book. Good luck and you got it.
