If Science notes make sense but graphs and tables confuse you, the missing skill is probably evidence reading rather than content recall. Scientific data asks you to identify variables, units, patterns, comparisons, changes, and sometimes anomalies before deciding what the evidence actually supports.
Practise describing the data before explaining it. State what increases, decreases, stays similar, or differs between conditions; check the scale and units; then connect that pattern to the scientific idea. This prevents the common mistake of jumping straight to a memorised explanation without first reading what the evidence shows.
Use the Science Learning Hub for subject-specific data questions and the Research & Inquiry Hub for the wider logic of evidence and interpretation.
