字学 is the kind of confusion you run into only when you learn simplified Chinese. If I have to interpret 学, it looks more to me like a person sitting in a house on fire; whereas the traditional form 學 is a man holding 爻 in his hands in order to learn his fate, hence "learn". Similarly, 覺 is one who sees (見) his fate. Chinese characters are created with all sorts of clues for you to pick up. It is unfortunate that some of these clues got taken away with the simplification of the language. 學 is not only more distinguishable than 学, but takes the same amount of effort to type.
