the key to solving folding problems is to do retro analysis, start from the end and try to open each fold, keeping in mind where the holes are. i hope ur talkin aba the same folding. there is also an easier way, there are only 4 possible first folds, u can use square papers to create the first 4 folds, once u have them follow the folds the question asks and then it will be easier to view the folding concept. pm me if u need me to clarify i'll draw and scan it.
