Work on basic flying...holding it level, turns, descents/climbs/level offs, pattern and landings, etc. Those are what you'll start with anyways and that's what will build a good base for something like IFS. As much as you can, get used to how radio comm goes. Not much you do at your local airport will emulate IFS, UPT, etc. but the more you can fly at a towered airport the better. The comm "overload" will actually make you better. Do all those things and see if you can get 15 hrs in and solo possibly. That would be a great boost going into IFS.
