ok heres my question ... I've had a private pilot multi engine land w/ instrument for about 2 years now and I just finished my single engine commercial w/ instrument. So my question is about my multi add on to my commercial. I've heard about 10 different things from various cfi's. Does any one know what the test is for the multi add on to commercial? Shouldn't it be just a few prep hours and then a couple commercial manuevers and finish w/ an approach? Since I already have my private multi instrument? yes no maybe? Any help would be much appreciated

Thanks
