Using the Questions Screen
When you have selected a skill the Questions button becomes live.
Tap the Questions button to be taken to the Questions Screen where you will see two practice questions for that skill. There will also be a reminder of the key points from the skill screen and one of the two example diagrams.
Depending on the nature of the skill questions either require numeric answers or multiple-choice selections.
Numeric: Unless the questions says otherwise, always round correctly to ONE DECIMAL PLACE before entering your answer in the box. Some questions naturally need more accuracy and they tell you the rounding required.
Multiple-Choice: Enter the letter of your choice in the answer box. It is not case-sensitive.
Then tap the Mark button to find out whether you got it right. You will get a tick or a cross as feedback.
Tap the Answers button to find out what the correct answers are.
You can do some working on this screen in areas not used for diagrams or questions. Just write with your finger on the screen. There are some readymade shapes to help, like triangles and rectangles. If you choose Erase from the colours toolbar you can clear small parts of your working. You can tap the trash icon to clear your working completely - it will not affect the questions.
If you need a calculator remember that a 4-finger upward swipe will let you quickly access other apps on your iPad.
