Hi, I strongly recommend you to study UG in abroad, if you have the marks and money and survival instincts. UG in India is good in some of the Top Universities or colleges but a large chunk of good colleges are far out of reach of students as the requirements could be 95% and above. Whereas with a good 80% marks, you can get in to Top Universities around the world. Plus the exposure of studying abroad will you a mature person. There are always challenges for a young kid to pursue UG or Masters abroad. But most Indian students adapt quite well after the initial hiccups and have done remarkably well. But selecting a right course and right University plus the right country will be very important. When it comes to admission abroad, you need to plan admissions well in advance plus if you are looking for Canada or US, you are required to write SAT plus TOEFL. So wish you all the best.
