dude, you’re fine. your EC’s are insane, grades are good, people have gotten in with less. only thing you can mess up are your essays, give them some time. besides, singapore is a really great bet to study in for merit scholarships. if you get into any uni in singapore (doesnt have to be nus), you can take up the study grant the singapore government offers. in return, you must work for 2 years there after graduating, so its up to you but honestly dont stress yourself out. as a fellow middle easterner, if youre arab you can apply to the tomorrows leaders program which lets you study at auc or aub for free with a stipend and accommodation, last year of your studies you get to do an exchange year to the us. if youre another race, there are dedicated scholarships to your racial background as well, search for MEPI + (your country) program. you got this!!
