My teacher told me that the examiners use similar questions to previous years so you can spot patterns.
Does anyone know or has found any patterns in previous edexcel papers? like what sort of questions do they always put in?

they repeat loads of questions.
Make sure you can explain why SiCl4 reacts with water but CCl4 does not.
Make sure you can explain the change in lattice enthalpy and using solution enthaplies to explain the solubilities of sulphates and hydroxides.
