23 Equations

Learn by heart all of the Physics equations you need for your GCSE exam, then practice using them until you are perfect. Learn Physics independently.

So, you've got to learn loads of equations for your GCSE Physics exams. There’s no way around it, calculations make up at least 30% of the Physics exam so the better you know the equations, the better your grade is going to be.

Now, you've got them off by heart. Time to start using them to answer questions. The smart models generate questions with values that are never the same. The smart models will be help you if you are stuck: suggest the next step or show you a similar example answer. Use the built in scientific calculator to work out your answer. Then, the models will work out accurate feedback, on your answer and show you how you should have done it. Then you can get it to give you a similar question to practice what you've just learnt.

The app works like a virtual pack of index cards always at your fingertips. All the important information is there, including the units. Tap on the equation to re-arrange it, even go back step-by-step to see how it’s done. Add comments, give them a star rating and emoji to keep track on how you are doing.
The Q button lets you try practice quizzes to test your memory and answer questions and take test.

You can sort the cards, focus on just one topic and keep track of how you are doing over time.

There are nearly 80 models giving nearly 500 different combinations of variables and, with different contexts, there are nearly 1500 variations of questions. But the values used in each question are intelligently generated so you won't get exactly the same question twice.

Key features:
• All the equations you need
• Rearrange equation and go step by step
• Learn units and variations
• Non-stop questions for each equation.
• Smart models guide you to the answer.
• Detailed feedback on your answer, including model answers,
