Proper assessment would require an exam and testing. There are no simple answers to this question. If you are concerned go in for an evaluation.

77 inches, 6 ft 5 is taller than the average, but may be reasonable depending on your mid-parental height. If possible, check in with your doctor to see how your height has increased over time. At 22 years, it is unlikely you will grow more.
