Dear Nandini,

Your interest in archaeology is commendable. Most colleges in abroad require high score in GRE. Also please check the eligibility criteria of the college you want to apply to, for example, you may need to prove your English Language skills through IELTS or TOEFL. Most colleges require 5.5 in IELTS and 80 in TOEFL. However statistics differ from college to college. If the above mentioned examinations are not considered in the college you want to apply to , there may be SOP writing, Skype interview or any other admission procedure followed. Also keep at least 2 positive recommendation letters from your professors. Really helps in boosting your chances for admission. All the very best!
