Study design Biology IMPORTANT

[biology1234]

Hello everyone,
I had an important question. As the study design for next year has changed. Are the old exams that are from the 2016-2021 study design still relevant and good to use. Is this a disadvantage and are their any tips as I am really nervous. Are their any other resources that would help.
Thanks

I'm doing the current study design and I also had a look at the new one. I would say there is quite a noticeable difference, with more emphasis on crispr cas 9 and more depth into fossils. Things that rarely change in bio are the photosynthesis, aerobic respiration, anaerobic respiration and immunity. What units are you doing next year? If you're doing 1/2 next year then don't worry.
