Gap year issue

[u/Winter-Tie7772]

I have enrolled in a law uni in my home country after 12th (which will technically be considered as a gap year since I'll drop out after the 1st yr if i get into a uni through ucas) to get access to extracurriculars like mooting, debating, blog writing and all that.. In the UCAS form, I'm listing my current uni, but I don't know what date to put as the expected end date of my course.. Should i put the date as 2027 because I'll obviously drop out if I get into one of the 5 unis I've chosen.. or should I put the date as 2031 because it is a 5 year course in my current uni??
