As others have mentioned, it tends to "click" after some hours so don't worry too much.
However:-
Different instructors work differently. I flew with 3 or 4 different ones, basically due to varying availability, and similarly in different planes. I spent some 10 hours with one instructor who demanded NDB holds to perfection (within 5 degrees on both legs) which I now know is stupid, especially as this being nearly the first thing we did. Some put you under a lot more pressure than others. Some have no idea what you actually need to be able to do right. Try to find an instructor who flies IFR for real, they approach things much more practically and you will learn more actually useful stuff. The IMCR syllabus is very vague and IMHO the absolute minimum isn't enough for real flight when you look at the really great privileges you get.
Flying a knackered plane in which the DI drifts 10 degrees every 10 minutes (not kidding) makes tracking any navaid FAR harder. The instructor won't tell you that, of course, he just works there. I've had instructors tell me that badly drifting instruments improve your scan ...a total load of tosh... So be choosy about what you train in - it will save you money. Pay extra per hour for a better plane if you can, or go to a different school which has a better plane. It makes a BIG difference. When you fly in real IMC on your own, you sure as hell won't want to do it in something clapped out, so why learn that way?
Try (and this is going to be controversial) to find an instructor who will train in actual IMC so you don't have to wear foggles. Obviously doing it under a Radar Information Service is a good idea. It is a lot easier to fly in actual IMC than to fly under foggles or especially that ghastly "tunnel vision" black plastic IFR hood, especially if you have to do other things like reading an approach plate. Of course you will never fly with a hood yourself for real!
Unlike with JAR ratings, the same person can also do your IMCR skills test.
Also you can start above the clouds; it is easier on you but is good practice for navaids because you won't have a clue where you are.
Flying in IMC on your own later (when you've passed the skills test), or perhaps with a friend who is IMC/IR, is a lot easier than with an instructor because the pressure isn't there, and you've got enough work on as it is. Flying is a constant learning process and you will learn while enjoying it.
Finally, you can fly VFR in any old piece of junk with crap or missing avionics, and many do. Doing the same in IMC might be legal (outside controlled airspace etc) but is awfully hard work. So you will be looking at getting into something better, and this will very much affect what you rent, buy into, or buy outright. If you want to fly a lot of IMC then an autopilot, even a simple one, is pretty well essential otherwise you will be like a zombie when you arrive. Same goes for currency; unlike VFR you can't just drop it for 6 months and then go up into the clouds.
