Hi.

According to CDS Exam eligibility criteria, for Education Qualifications, it states that

Candidates who are studying in the final year/semester Degree course and have yet to pass the final year degree examination can also apply provided candidate should not have any present backlog upto the last semester / year for which results have been declared upto the time of submission of application and they will be required to submit proof of passing the degree examination at the time of commencement of course to reach the IHQ of MoD (Army)

Therefore, if you have backlog of a whole semester then you will not be eligible, only after clearing the backlog you can apply for the exam.

Good Luck
