INSTRUCTIONS
The MATHEMATICS EXAMINATION PRACTICE AND TESTS tape is arranged as eight separate loadable programmes. The first of these programmed gives all the details relevant to the tape and should be run prior to running any other programme.
On side one of the tape the programmed "directions", "Section 1 ", "Section 2", "Section 3"
and "Section 4" are recorded.

Each programme can be loaded independently in the normal way by loading the programme names given above.
Additionally at the end of each programme, the next program r Me on the index can be loaded automatically if required.
Each question contains five possible answers. To select the correct answer press a, b, c, d or e (as appropriate) then ENTER. Errors can be erased by pressing DELETE (caps shift and 0)
Following the selection of the correct answer you can Coke to the next question by pressing SPACE or run the sample answer by pressing ENTER
If the selected answer is wrong the sample answer IS displayed automatically.
After a scruple answer display press SPACE for the next question or ENTER to rerun the same question.
At the end of each programme press Vinyl to load the next programme, press ^l^lr^l^l to rerun the same programs or press "a" to goto BASIC.
At all ports In the programmed where a user response Is needed you will be prompted with the arrogate options. Therefore it is NOT necessary to memorise these Instructions.
MATHEMATICS EXAMINATION PRACTICE AND TESTS is designed to embattle a student to revise all of are Mathematical techniques required for the core of the C. S. E. and G. C. E., O level mathematics syllabuses.
Throughout these programmed emphasis has been placed on allowing the student to practice bas^i saris and techniques and to reinforce these detailed worked solutions when the student has answered a question incorrectly, or feels that further information is required.
This material has been created by the publishers of Celtic revision aids and is designed to aid students in the final stages of their revision work with particular emphasis on practising techniques and examination styles.
