I was still overwhelmed with the IFR rating, after I got it.
My IFR training, in retrospect, was just too rushed.
Instructors, generally, want to help you get thru it as quickly as reasonably so you don't have to spend more money than necessary.
What I should have done was spoken up and said, "Can we slow this down a bit? Can we just go up a fly a couple of stupid-simple straightforward flights, with no deviations, no emergency procedures? Just let me get comfortable flying a few simple, straight forward ifr flights? I didn't do this.
Instead, every single lesson was none stop deviations, emergencies, equipment failures, multiple different approaches on each flight, etc.. It felt more like Niagara Falls than just a fire hose.
I get the fact that most real IFR flights will have all kinds of unexpected changes so it's important to train for this. However, in my case, I wish I had just asked to slow things down at times. I should have spoken up at the time but didn't. I guess I thought the instructor new best. I was wrong and wish I had realized this at the time.
In my case we had half a dozen airports with approaches within 15 minutes of each other and there was never any time at all to breathe in between.
In the end, the never-ending fire hose training was not right for me and I only flew one solo ifr flight before giving it up.
Not saying this is your case, but just something to think about.
