What will I be graduating with?

So my second year is worth 30% and my last is 70%. I had a tough time at uni and barely making it through, my second year I averaged 45% and these r the grades I got:

88%,50%,57%,57%,40%,56%

I would really appreciate if you much the overall degree classification I’ve achieved with these. Thank you.

I'm kind of impressed by the 88%. What subject is this in?

Using final grade = weight1*grade1+weight2*grade2, and presuming all the modules in yoru final year are equally weighted....
Final grade = 0.3*45+0.7*(88+50+57+57+40+56)/6 = 54.1

You would be graduating with a 2:2, which seems reasonable considering the grades you got.
What are your plans now considering the above?

My bad , the 88% was what I got in the exam. For the overall module I only got 79% :/
This was for thermodynamics and energy systems (I study mech engineering)
