Would dropping out of uni to apply to a new one look bad on my application?

Dropping out of my 1st year of uni to fully dedicate my time to my new a levels and apply to imperial/ucl. Would this look bad on my application. I'm not sure if it would even be mentioned because I haven't completed any modules yet therefore I haven't received any grades so I'm not sure if they'd even know but regardless could this look bad in anyway or?

You must declare incomplete undergrad study in your education history.

If you’re changing subject or retaking AL’s to aim higher, it won’t disadvantage your new application at all. Uni’s don’t care.

Ok, so incomplete undergrad study won't disadvantage my app to imperial.

Yeah, I'm dropping out simply to focus on new a levels which I haven't previously took to attend a new uni for a different course
