Dr. P A & AS Level Chemistry Definitions Revision app for iPhone and iPad

Dr. P is an exam-focused interactive tool to help you learn definitions of scientific words and phrases. All AS / A-Level exam boards are covered, and by tailoring to each board we’ve been careful to satisfy the precision that examiners look for when asking you to define or explain scientific terms.

Knowing your definitions is a good idea, not only for the marks that are directly for defining or explaining terminology, but also, if you really understand what a scientific term means, then you are much more likely to successfully apply your knowledge in other contexts. This kind of application will be the key to higher grades, so learn those definitions!

Dr. P cuts each definition in half and then helps you ‘Learn’, ‘Play’ and ‘Test’.
• When Learning, you choose which half of the definition is shown, and then the keywords from the other half are revealed one at a time at your own pace.
• When Playing, you choose which half of the definition you can see, and you type in the keywords for the other half. You can have hints for the length of the words – a bit like hangman! When you get things wrong, the corrections are shown and you have the chance to repeat that definition straight away.
• In Test, you have to give all the keywords for the whole definitions for up to 10 terms. Dr. P marks the test and shows you how you did at the end.

You are in full control of which topics of AS or A level you are working on with Dr. P at any time. Just go into Settings and choose the paper and topics. These will then be kept as default until you change them.

As you use Dr. P and get definitions right, your Confidence Score will increase. Each definition has its own Confidence, and these come together to give an overall Confidence for whatever topics have been chosen at that time. But, if you don’t use Dr. P regularly, your Confidence will go down, so you need to keep practicing! The Confidence scores for each paper, topic and term can be looked at in detail at any time by tapping the score on the front screen.

Dr. P knows alternative keywords, so you don’t have to learn the definitions absolutely word for word. For example, “a substance which” and “a chemical that” are both fine. There are lots of alternatives that Dr. P knows, but there could be others. If you use Dr. P and you type something that isn’t allowed but you think it should be, you can get in touch and e-mail your alternative to:

feedback@drpscienceapps.co.uk

If we decide it’s allowable it will be added to the alternatives, and as Dr. P checks for changes to the definitions regularly, you could see the result of your e-mail quite quickly.

We hope you like the app and find it useful!
