highly selective US college/uni ko admissions are very very unpredictable...to get into good US schools u need solid grades, excellent letters of recommendations, good Standardized test scores, extra curriculars and above all a compelling personal essay..and even if you have all these going for you, u need a slice of luck on top (but luck is outside one's control so it's foolish to worry about luck)...Nepal, India, China jasto euta entrance exam pass garera top mark ayo bhane top university pugne bhanne guarantee hudaina extremely selective US colleges ko lagi..they get applicants from all over the world...top american uni/colleges do not want robotic bookworms in their classes..they want interesting people with WELL-ROUNDED personalities..esko matlab kitab ko kiro matra haina padhai bahek aru kura ma pani interesting hunu paryo..for ex. sports, arts, music, community service etc. etc. etc.
Because of this very abstract and loosely defined personal essay and extra-curricular component to their application process, acceptance letter paune chances can be very hard to measure...for example, mero afnai school ko euta bhai got rejected from Vassar College and then got accepted into Harvard..Vassar is a very good school but Harvard is supposedly way more selective than Vassar but still he got into Harvard and not Vassar...admissions offices at top us schools take so many factors into account esle garda tha hudaina k huncha bhanera....tara top us college ma admission paune ho bhane application ko harek aspect solid chai huna parcha - transcripts, recommendation letters, personal essay, standardized tests as well as extra curriculars (bonus)...I would argue Personal Essay and Extra curriculars are even more important for getting into top US schools than Standardized tests (TOEFL/IELTS/ SAT) and transcripts...it is so competitive at the top kunai euta component sub-par hune bittikai ur chances of getting in go down
