You don't have to practice in a Frasca. That would be the best option I suppose, if you have the money and access to one. The only thing I did to prepare for a sim eval was fly the default baron on MS flight simulator. Is it as good as getting in a real frasca? No, but I assure you it was more than enough and better than nothing. Just a thought and an option for those that don't have access to a Frasca.
