ExplanationQuestion 6
This question discriminated well. The most common incorrect response was B, chosen by candidates who placed nucleoli before lysosomes; a nucleolus (1–3 µm) is larger than a lysosome (0.2–0.5 µm).
Ribosomes (≈25 nm) are the smallest of the four structures listed, which rules out A and D immediately. The correct answer was C.

Loved by 5K+ users in 100+ countries
I enjoyed the range of subjects to choose from, especially the not so popular ones such as further maths. it's very difficult to find topicals for those so thank you for that. I like that you are able to look at the direct mark scheme from the question, really gives you lots of control, and rare to find. it is a really nice experience and I couldn't have completed my A-levels without this website and I will be sharing this with more people. Thank you again :)

I love how Open past paper was very easy to use and study for my exams as it has topical past papers. I feel like due to open past papers ive been performing good in my class tests. I recently had my AS test and I used open past papers for it. If I could suggest anything maybe I would try adding a video to that specific question on how to solve it since some users wont understand the process of getting the answer from the marking scheme.

It's honestly great! I really enjoy the increased number of questions that can be generated and that we can select individual questions and generate a paper. It is particularly helpful during exam preparation since I can go back to papers I've completed and generate a paper of questions I got wrong previously.

I always struggled with exam prep but this allows me to customise my learning and I can't express how grateful I am that you took your time and effort to create this platform. Thank you so much

It really good, if I was to give one thing that could be added it would be to create a section where you can see what questions you got wrong and which ones you got right in order to see which topics you need to spend more time on, or just which sections within the topic you are struggling with.
