Where can I find ionic bonding past paper questions by topic with the mark scheme?

On DABOURHUB every ionic bonding question is grouped by syllabus point and shown with the mark-scheme wording, so you can see exactly which sentence earns the mark instead of scrolling through whole year papers.

What is the most common ionic bonding exam question and why do students lose marks on it?

The repeated pattern on IGCSE papers is a short stem that asks you to apply ionic bonding and then justify it with a command word (explain, suggest, compare). Marks are lost by stating the fact without linking it back to the wording of the question, so each ionic bonding item here is written as a full-mark answer.

Is there an alternative to Save My Exams or Physics and Maths Tutor for ionic bonding?

Yes: the ionic bonding notes, topical questions and MCQ quizzes on this site follow the same syllabus headings as the official specification, and they open straight from the search result with no download step.

How do I revise ionic bonding in two weeks before the exam?

Three passes: read the ionic bonding notes once, then do the topical questions and mark them against the mark scheme, then redo only the ones you missed. The quiz on the page gives instant feedback so the third pass takes minutes rather than an evening.
