The probability is high, but getting into a university in the U.S. is not everything. If you want to stand out as a strong candidate, I recommend taking the SAT or the ICS. However, if your goal is to enter an Ivy League university, I suggest focusing on being unique and finding something you genuinely want to pursue for the rest of your life, whether it's research or creating a social project. If you don't get accepted or haven't found your true passion yet, you can always consider attending a university closer to home. Once you're ready and have discovered that conviction, you can apply to an Ivy League or any other U.S. university. But don't stress too much about it. Remember, it's not the only path. Even so, I am also sure that I want to attend a university in the U.S.
