It is not to bad..You are well prepped in ground to get through it all. Just know all the stuff that they gave you in the handout cold. All the memory items and the limitations

The sim is a different thing all together. You need to have your profiles and flows down cold before you get there. And when I say cold I mean...Cold! You need to be able to say them without thinking about it. (Like the micro machine dude) Prime example is the non precision hand flown approach. If you have to think about your calls you will screw the pooch. The sim is fun but it really shows where you are as an instrument pilot. Just make sure your scan is solid or you will struggle with the approches. So go out and hand fly approaches to death while you can it will set you up for a sucsessful sim.

Good luck! Hope you get in soon for my sake
