It all depends on what kind of flying you do now, and how much IFR vs. hard IMC you get.
If you fly IFR in VMC a lot, you should be pretty good on the rules and procedures, but might need some gauge time. Get some hood time with a variety of approaches, including single-engine or partial panel if applicable.
If you don't fly IFR at all, then try a XC or two in the system before you do the approaches. You could do the XC VMC with or without a hood.
If you get a CFII to give you some "checkride prep" ground, that should suffice.
