Revision List - Grade 10
Annual Examination 2007
It is suggested that you review past notes, homework and tests. The format of the exam questions are
very similar to the questions found on CD included with the book. The main focus of the exam will be
on the topics we discussed this year:
 Overall Computer Features
 Computer Hardware
 Peripheral Devices: Input and Output & Secondary Storage
 Programming

Manage your time wisely when you are studying. Avoid revising at the last minute; it creates
unnecessary stress. Proper time management is essential. Try to revise a bit each day and find the best
method that works for you. Some suggested ways are flash cards, mnemonics, and jiggles, creating
your own test and/or study groups. Consult me if you need further assistance with any difficult
questions or any of the suggestions.
