If anyone failed in the MAKAUT practical exam, is it considered to year lag?

MAKAUT practical exams depend on a variety of factors ranging from your lab attendance to your viva. Many MAKAUT colleges give practical marks based on how frequently you attended the lab sessions. Your lab file check-in on time might also be considered at times.

Another major criterion in your MAKAUT practical exams is your viva as it directly affects your grades. The average practical exam score is 7-8 but with a better viva, you can increase your score up to 9-10. 

Short attendance may result in failure of practical exams which in turn becomes a year lag. So, don't underestimate the importance of MAKAUT practical exams.
