Even if it is an accepted A level, it is difficult to score well because very few people actually take the subject and it is graded on a bell curve. Furthermore, the marking criterion keeps changing, and teachers don’t know how exactly to train their students to do well. A good logical mind does not always equate to giving examiners exactly what they are looking for.

Hence, while it is a worthwhile pursuit to consider the construction of knowledge, and certainly interesting as a topic, I do not think that KI is necessarily good for a student to take at A levels, even if he fits the bill.
