Why do you think that ?
And what do you mean classical? Classical is usealy described as english, maths, science etc.
Classic programming like ... COBOL
Actually, this course looks pretty good. I remember reading about this a little over a year ago and that there was a lack of good game related courses in Britain. I can't remember if the discussion was on the SplashDamage site or LevelMakers. Generally, the conclusion was that having a solid education in computer science was the important factor. The Harrow course outline hits on the two critical languages (C++ where most of the industry is, and C# which is emerging). The concern I would have is that they may not concentrate enough on either to be of huge value without having to do more.
A good way to check out the quality of the course would be to talk with someone that has taken it or is currently enrolled.
Either way, good luck.
