Since the final year project is for a year, I kept putting it off for handling my more urgent school projects.
Is the above sentence grammatical?
I am talking about final year project during the time of my university.
I use is, since the final year project is still for a year now at 2015. I use kept, since it is an event in the past.
From comment: For my context, I am talking about the final year project during my undergraduate time (it is like 10 years [ago]). The final project is a project that lasts for 1 year (two semesters), e.g., 1 Aug 2010 - 1 Aug 2011. Therefore "the final year project is for a year" I am talking about a fact in the university that I have attended before. In such context, does it still look unnatural or ambiguous?
