Start with one narrow topic
Pick a subject you recently studied and write ten solid questions with explanations. Narrow focus produces clearer content than trying to cover an entire syllabus at once.
Write explanations students can learn from
Every answer should teach. Mention why the correct option works and why common traps fail. That is what turns a quiz into a learning tool.
Iterate with feedback
Watch which questions get missed most, then revise wording or add a clarifying blog post. Publishing is a loop: create, observe, improve.
