COMPUTER STUDIES



These programs are designed to help you gain success in

CSE, 'O' level, 16+ and 'O' Grade examinations. All the main

on the particular area you have just revised. You should use

the programs in conjunction with your overall revision

programme.

   There are four types of program on this casette. Some

programs cover a wide range of topic; others are more

specific. If you only wish to revise particular parts of the

syllabus you may find the topic you want by referring to the

to make a note of the number on your tape counter where

each program starts. You can make a note of the numbers in

the boxes below. You can then go straight to it when you

want to find a particular program.
