Some educational systems are based on memorizing informations. The type of exams requires the learners to write what they have already memorized and lacks any creativity, critical or independent thinking! What is the use of memorizing like a parrot?! Nothing is added or created, just the same information is repeated. The learners will not be able to see, analyse beyond the surface; they will think 2+2=4 . But critical thinking teaches us that it is not always the case. Creativity makes us to understand that there are more than one answer to a question depending the circumstances.
