Which subject is easy to get exemption among isca and idt

differs from person to person but i think you have more chance to get exemption in idt as this is the only paper where in every attempt the checking is lineant but you never know icai can always deliver a bouncer like in nov 15 attempt idt paper was very much unexpected but then also checking was good.So you should go with idt as more importantly gst is also be applicable from nov 17 which u can escape if u get exemption in this attempt..
