As per your query of being able to sit for the 3rd-semester exams are coming in December, I think the time for filling the examination form for the current period might have already finished, if not, kindly contact the college exam cell for the filling of the application form. Some of the common criteria followed by engineering college or university are:
i) A student can only keep 6 papers in 1 year to move forward or get promoted to the next academic year i.ei not more than 4 theory subjects and 2 practical/ project subjects on the basis of combined result of both semester examinations of a particular academic year.
ii) As per clause 8.4, The pass marks in each theory subject (including sessional marks if any) should be 40%.
iii) As per clause 8.5, The pass marks in a project/practical subject (including sessional marks if any) should be 50%.
iv) As per clause 8.7, The pass marks in Seminar, Industrial Training and Educational Tour, Viva etc, should be 50%.
v) As per clause 9.2, A candidate should satisfy the requirement of clauses 8.4, 8.5 & 8.7, he/she will be eligible for provisional promotion with Allowed to keep terms (ATKT). He/she can choose up to a maximum of any four theory papers of that particular academic year as per his/her choice to pass the examination of that year.
As you have 2 backlog in 1st semester and 4 subjects of 2nd-semester, it makes a total of 6 subjects of the first year and now in 3ed-semester, you may have more 4 papers to appear. That makes a total of 10 Papers. As per my understanding, you have a backlog due to your health issue and if you try well, you will be able to clear your back log in this attempt itself. Please focus to clear as many papers as you can and try to clear your 1st and 2nd-semester papers during your 3rd or 4th-semester attempt as many universities do not allow a backlog of 1st year(1st and 2nd semester) to carry forward to 5th semester or 3rd year. This can make you have a one year gap.
Try to clear your backlog at the earliest as this will help you score good marks in your coming semesters and get a preference for campus selection. Please note that many companies do not entertain more than 2 Allowed to keep terms (ATKT) in a year and this will take away your golden opportunity of getting into the best company of your choice. Try hard and all the best for your coming exam.
