Does anyone have any predictions of what you think is going to come up for the unit 3 exam on the 17th

Wait what exam board do you do ? Mines Pearson and I have mine on 17th jan

what do you think the method will be for the 12 marker and 8 marker? (for the unit 3 paper on the 17th)

I think chemistry is definitely coming up because the last time it came up was in January 2023
The last paper had bio twice
Btw the 12 and 8 marker are part of the 2nd section so they both will be the same subject

Chem and chem or chem and physics

I think chemistry is going to be part A because it hasn’t appeared in any papers since 2023 and part B probably physics as it came up as part B last year (biology came up as part A so I doubt it will come up again as part A)

Idk how smart Pearsons are, not trying to underestimate them, they could be reading our convos and decide to change it, just to make our lives a living hell. However, based on probability i calculated that, Circuits have a higher chance of appearing, it isnt clear for which section im afraid. But also looked into enzyme, Based on the potential 4-year 3-year 4-year cycle, enzymes has a strong chance of appearing in January 2025 for Section B.
Obviously, I’m a genius, but let’s face it—probability is just an estimate. The data suggests a pattern, but that pattern isn’t set in stone; it could shift at any time. Now, you’re probably wondering, “Why not just revise instead of spending time calculating probabilities? Well, here’s the thing: working out probabilitiesor getting close to it is an exercise in problem-solving.
It requires an interpretation of loads of information, arranging information in order, and then taking one piece of information at a time to try and make an accurate forecast. This process sharpens your ability to view things from multiple perspectives, which, in turn, solidifies my claim to genius status. Of course, I’m not claiming to be 100% certain probability never guarantees certainty. But I’ve analyzed all the patterns and trends in depth, and I’ve done my best to make accurate estimations. Let’s hope they hold up.

Most Likely Pairings:

1.

Enzymes in Section B + Circuits in Section A

2.

Enzymes in Section B + Diffusion in Section A

3.

Enzymes in Section B + Energy in Section A (less likely)

Final Prediction:

Section A: Likely Circuits (~50%) or Diffusion (~30%).

Section B: Enzymes (~60%).

Energy topics (Energy/Contents) appear every 3–4 years. The last time Energy appeared in Section A was June 2022, so Energy could also return in 2025. However, Energy has appeared more recently than Diffusion or Circuits, so it's less likely unless the pattern breaks.

Final thing: Goodluck to all, especially those who are sitting the exam tmr, i apoligise for not working it out sooner.I wish the very best in y'all future scientists:smile:

what should i use to revise the blue revision guide ?

I think they scared that i worked out a probability for what might come up in the unit 3 exam

I meant the 17th i got the dates mixed up

what should i use to revise the blue revision guide ?

Just study the main topics such as standard deviation, chi squared those are worth alot of marks maybe 7 intotal, u only need 41 to get distinction, should be easy, know how to plot a graph, bar chart, form a results table include each number to the same decimal place, study invesigation titles for all of diffuision, temp,conc ect, do the same with energy, carbon chain legnths, do it for enzymes, pH, conc, tem, know the difference between posirivwe and negative correlation, method steps for all...

how should i study investigation titles ? rn im just going through the whole of enzymes, circuits, diffusion and energy using the revision guide is that good ?

in 2023 (jan) for section A it was resistors and circuits and section B diffusion . Does that mean your probability will change ? and for the 2024 (june) section B was circuits

In Jan 2023, for section A it was enzymes, for B it was circuits, for June 2023, it was Circuits and Diffusion. Im sorry if i confused you, let me know if you have any other questions!

I went over the mark scheme for June 2024, it was DIffusion and (Sampling) Plants

How to revise for the 12 marker

My message keeps getting deleted, its fustrating me:/

Follow a simple structure such as:
Hypothesis, 3 variables, Risk assessment, Equipments with justification and finally the method steps (ideally 5 bullet points). Make sure to use command words. Without a good enough hypothesis, you may be only awarded 3 marks or so, even if your method was solid. I tend to write it all down everything again and again and again till i memorise it. You got this, and Goodluck!!!
