I am an international student and will give my board exams in 2016 and will not be able to provide the results in my application. But, I will receive my pre-board(conducted individually by school) results in December. Can I send those and my predicted score on the basis of pre-board results? If so, how to send predicted scores?
Without knowing your country, the evaluation process, or how predictive those ‘pre-board results’ are of your actual results, it hard to give advice. There is a forum for international students on CC which may be a better place to post this question. Students from your own country who have applied previously and been in this situation can give you the best information. Or if you school sends students abroad for college regularly, they may have the answer to this.
In general, you can always provide updates and information via email to the schools. If possible, for things like exam results which need to be verified, you want a third party to send in the results - ideally your school - with an explanation of why the predicted score is relevent and when he actual score would be available.
