If you fail in one of the subject of your degree course then you can write it next year with your juniors as a supplimentary examination. It is an examination offered by almost every colleges for those who failed their subjects. Hence you can write the subject you fail next year. This is applicable if you failed in all your subjects. That means you will definitely have to study the previous semester books again. The time limit for writing the exams. So please try to write the field examinations as soon as possible in the next attempt itself.

Thanks
