Extension for the deadline

Very Good Day Mam/Sir, Due to some reasons I didnt invested much time in the Trainity's Data Analytics Course projects. I learnt almost all the consepts in free time in last two mounths and now I have planty time to work on peojects and complete the course as my exams are over. I saw on dashboard that only three days are left. I will try my best to complete the projects but in case I didnt will there be any negative effects of taking arround 105 days instead of 100 days for compliting the couse. I know I wont be refunded but are there any other things that can be bad for me for taking few more days to complete the course. Thank You
