Basically SE involves increasing your superfree fruit/veg to 2/3 of your place and the other 1/3 is free. The other difference is that when you use syns you take the highest syn value rather than the lowest like on EE! If you use the search on here(and search just success express in thread titles)there are no less than 77threads ranging from how to do it, to people SE diaries to recipes
good luck, hope it helps x
