Late reply, but generally at The University of Brighton your first year doesn't go towards your final degree classification. Secondly, a pass (third class mark) at UoB is usually the minimum of a 40/100. If this holds true for your course, as long as you got 40/100 or above in all of your modules then you'll be allowed to progress to the second and third years of study without summer retakes.
Another thing to remember for your future assignments, unless you have a course leader approved extension or an extension that's automatically applied to all your assignments because you have a disability, long-term illness that interferes with your ability to study etc., every piece of work you submit beyond the normal deadline will be capped at 40% (a lower third class). I think at Brighton usually the second year of study goes towards 25-30% of your degree's grade average, and the final year is about 70-75%. So make sure you get stuff in on time if you want the best degree mark you can get 🙂
I hope that this helped.
