The person writing my UCAS reference doesn't know me

I finished college last year and was supposed to be attending Bath for Physics but decided to take a gap year and reapply to another university. Last year, I was applying for oxbridge so had the head of oxbridge admissions write my reference however since I am no longer part of the college and am not an oxbridge applicant I have to ask my form tutor from last year. I only had her for 1 half hour a week for 6 months, she doesn't know me or my work ethic and I'm worried that will reflect in my reference. Not just that, but she didn't really like me as I didn't go to many of her sessions as it was mostly just ucas preparation, which I had already finished by october. I did ask my previous physics teacher, who knew me for the full 2 years and got along with me quite well. However, he said that as per the college rules I have to have my form tutor complete it. Can someone reassure me that my reference wont be too important in my application. I'm really hoping to get into warwick and don't want this reference to ruin my chances.
