All pages/headings reflect the content covered in the T-level Science B1 & B2 content. The resource has gaps for the students to update with their own revision for each topic. The expectation is that the students would fill in the gaps themselves and use this is a revision tool. There is no answer key, as this is just a supportive document to guide their revision/research. The documents are available as three individual PDF downloads - Biology, Chemistry and Physics are included in the package.
