Those are only basic models that we should know.
Well, knowing the models itself is not good enough. Must know when to apply those models, when other model are more appropriate, and most importantly, must fit very well with the scenario and discuss it in the answer.
If you look at past year paper (I forgot June 08 o Dec 07), the examiner's answer use Bowman's strategy clock rather Porter's generic strategy, because Bowman's strategy clock is more appropriate, and that model is also criticise Porter's generic strategy which restrict itself either differentiation or cost-leadership.
Understanding the exam area is the most important matter... at least I believe in this.
