Dont do it.
Practical experience is far more important than a course.
Also, dont think that the computer world is Microsoft and nobody else.
There are other huge computer companies that make millions of pounds and people with skils in their products are also needed.
Companies like IBM, HP, Sun, SAP, Oracle and so on all have huge parts of the computer marketplace and people with those skills are also needed.
Dont assume you will walk into a job as soon as you finish the course.
