I have only a very basic idea of chemistry but I was able to follow and use this program with no difficulty. It presents and teaches the techniques of inorganic chemical analysis in a very entertaining and informative way. A teacher friend of mine said, and I quote, "Hallelujah! a superb *teaching* program at last!"

A comprehensive instruction booklet is supplied with the cassette, which loaded easily and displayed clear, precise prompts and options. Excellent use of colour and graphics to demonstrate various processes, sound is not used, but then again it is not really needed.

I could not find any bugs, and the program seems to be well error-trapped.

Fully recommended to O- or A-level students and schools. If I was allowed loose in a laboratory the program warned me of my almost certain demise, and this added an extra dimension of interest.

I would have liked to have seen some explanation of invalid entries and advice on the correct entry expected: but this is a minor quibble on an otherwise excellent program.
