6th sem backlog clear in 8th sem result of backlog to be came on after the admission date of iit m.tech so any problem in admission
Hii..
Backlog subjects are the subjects which you can clear in consecutive years but you have to clear them before or along with final year so that your engineering degree remains in the limit of four years. Limiting engineering degree have varies advantages.Its ok to have backlogs as long as you clear them before you get admitted for M.Tech. Number of previous backlogs does not count.
Hope this helps.
Best of luck.
