what's the problem of Giving GRE?? I am sure Good school will never admit u without fulfilling requirements unless u are too extra in some aspects .If you have graduated from NEPAL , it's not a big Deal give GRE and do your best!! rather then trying in a hurry and getting into average schools try hard ,give GRE and whatever required ,be one year late ,get into a good school!! my suggestion from my experience to all,particularly graduates from NEpal. YOu will get nothing here so exciting as u think there be prepared show your strength ,claim your position !! that's how I suggest you to start higher study here, if u are here in USA you must know it well!! good luck!!
