Hi I wanted to know you know the ornithine cycle do you just learn the diagram? Or do you need to know full information on how the whole cycle works?

The latter. I've seen a question where they disregarded any sketches of the diagram for marks. Same goes for the Calvin cycle.

Is it just me or is nothing really making any sense so far... We've almost covered everything and whenever I even attempt a past paper I don't really feel like I know how to answer..Any advice???

Practice is key tbh

But the Calvin cycle is to do with photosynthesis

Not the point - drawing the cycles and diagrams isn't what will get you the marks - knowing what happens step by step is what will. In the case of the ornithine cycle, I think you just need the overall equation (sorry, I was half awake when I wrote the last reply)

Oh it doesn't tell me the over all equation in my book does any one know that?
It's okay don't worry

I have 280 ums at the moment including an estimate for A2 controlled assessment do you think I can scrape an A? I had 246 UMS in as but my controlled assessment for A2 dragged me down. Im really worried i was so confident of getting an A for Bio

What did you get in the practicals? You're on track, and you got an A at AS, what are you worrying about hahah
As long as you get an A in the exams you're alright

Yep. Finished a while back. Praying the boundaries are lower.

Alright, well I got 27/8 last year and at came out with an A so its not impossible (granted that was AS). 29 won't give you a huge amount of UMS, so work hard on revising all the content! :smile:
