LLB grades

I have just finished my second year of my law degree and this year went pretty bad. All my marks are between 40-50. I am aiming for a 2:1 at the end of my course and next year is my final year. First year doesn’t count, second year weighs 33% of my overall grade and final year weighs 66%.
Is there still a chance I could get a 2:1 if I work hard next year?

Have you worked out why you did so poorly?

Yes there was a number of things that influenced the poor performance

And worked out how to avoid that happening again?
What's your second year average?

Yes.
It’s probably in the high 40s

Assuming it's 48 then you would need 66 next year for an overall average of 60. You also need to check your degree regulations because most unis have alternative methods of classification for near misses eg 58/59. These usually are based on improvement in third year.

I just double checked and my average is around 45. I also just got another essay back and got 65% on that. The essay weighed 60% of my overall grade for that module. Would this increase my average? Would I still need around 66 next year to get a 2:1?

Well, 45 is lower than the 48 I assumed but the 65 is good news.
Which uni is this?

Westminster

Are these your current regulations...

Yes

I can't see the 1/3:2/3 split you describe. Appendix B has a very different split. Am I looking in the wrong place?

@DataVenia is very good at these questions...???

Thanks for the mention.
The 1/3 vs. 2/3 split is in paragraph 7.3.4 on page 109. It's also worth noting that they ignore the worst 20 credits across years 2 and 3, and work with the best 220 credits only. The only "wiggle" room if a student misses the 60 mark for a 2:1 is that the "indicator score shall be rounded to the nearest integer". So 59.5 still earns a 2:1.
@OP, given that you don't seem to be keen on precision ("my average is around 45", and "The essay weighed 60% of my overall grade for that module" with no indication on how you did in the other 40% of that module, or how many credits that module is worth), we can only work in approximations.
As @ageshallnot has written above, if your year 2 average had been 48 then you'd need a year 3 average of 66 to hit the magic 60% for a 2:1. As your year 2 average is "around 45", you'll need around 67 in year 3 for a 2:1. (1/3 of 45 plus 2/3 of 67 is 59.7, but they'd round that to 60.)
Edited to add that Appendix B isn't relevant as it's entitled "Undergraduate Award Requirements – Pre-2017/18"

Thank you so much for the explanation. I didn’t get the mark back for the other 40% of the assignment hence why I didn’t mention it. That makes sense, once again thank you so much for the explanation. Truly appreciate it.
