Which mocks do sixth forms actually look at?

I'm so confused. Some teachers at my school are saying that we must do well this year in our year 10 mocks and treat it like the real thing, whereas other teachers are saying that it's not that deep and the mocks in year 11 are more important and will be sent off to your sixth form. Which is it? Can someone give me the right answer?

Hello!
Your Year 10 Mocks should cover all paper 1 content for most of your subjects. Therefore, doing well on them will consequentially affect your revision for Y11 Mocks, which build on all the Year 10 Mock content with the added extra. Acknowledging this, do best in your Year 10 Mocks as even if they may be futile, in a crude manner, when applying for the Sixth form, they'll indirectly supplment your Y11 predictions as they affect your performance on the mocks they're based on.
If you have any more questions, please do reply!
(I am in Year 11, currently)

mocks in y11 (esp the december ones)

hii, im in year 11 and im doing my mocks right nowww. my school mentioned that sixth form will look at these mocks but do you know what exactly they take into account/what data they draw from them??

They usually use these mocks to make your predicted grades, for some schools they use your previous assessments to get a better accuracy for example if you were getting 5s all year for maths and suddenly got a 9 in mocks they may decrease your predicted grade due to that. But obviously your mocks are the main deciding factor to give you your predicted grades which will be used by sixth forms to give you conditional offers.
