Hi there. As board results were being declared after the completion of BITS application. If you want to fill your class 12th Marks in BITSAT then you can check the BITSAT Site for updates as they will might upload a column for uploading of Marks at BITSAT application but as in last year you will have to upload the marks in Application form of Admission as when being applying for admission in any of the BITS Campus. You will have to upload your mark sheet at that time and will even have to take in the Campus when you will go for the first time.
