This disclaimer applies to everything on yourscienceonline.com (“Your Science Online”, “we”, “us”), including our notes, practice papers, mark schemes, worksheets, calculators and blog posts.
Educational information only
Our content is written by a qualified science teacher to help students revise and teachers plan lessons. We work hard to keep it accurate and up to date, but we cannot guarantee that every page is free from errors, or that it matches every change to an exam board syllabus. Always check your current syllabus and follow your own teacher’s advice.
No guarantee of exam results
Using our notes, practice papers or lessons does not guarantee any particular grade or exam result. Results depend on many things, including how each student studies and the exam itself.
Not affiliated with any exam board
Your Science Online is an independent website. We are not affiliated with, endorsed by, or connected to Cambridge University Press & Assessment (Cambridge International), AQA, or Pearson Edexcel. Names such as Cambridge IGCSE, AQA and Edexcel, and syllabus codes such as 0620, are used only to show which course our content supports. All trademarks belong to their owners.
Practice papers and past papers
Our practice papers and mark schemes are original material written by Your Science Online. They are not official exam board papers. We do not host official past papers; our Past Papers pages link to the exam boards’ own websites, where official papers are published.
External links
Some pages link to other websites, such as exam board sites. We do not control those websites and are not responsible for their content, accuracy or privacy practices.
Advertising
This website may display advertisements, including ads served by Google AdSense, to help keep our resources free. Ads are chosen by the ad provider and do not mean that we recommend the product or service. See our Privacy Policy for how cookies are used.
Tutoring and calculators
Our calculators are learning aids. Always show your working in exams and check answers yourself. Information about online lessons on this website does not form a contract; details are agreed directly with each family before lessons begin.
