Dear student,
Since you mentioned that you missed an exam due to unforeseen circumstances it is possible for you to retake the exam. You need to contact the head of the department of your course at GGTU Banswara and provide a valid reason why you could not appear for the exam. They will then help you retake the exam in the upcoming semester based on the current syllabus.
We hope this helps you. Feel free to ask any questions you may have.
Thank you.
