Whenever I start a new thing, I begin with the absolute beginning. For eg:- If I start studying electronics I will go back to discovery of electricity, discovery of electrons, cathode ray experiment etc. Similarly with other subjects. I just understand things much better this way. So does this happen with anybody? There are times when studying advanced maths that I start wondering about how additions, subtraction are defined. I just like starting from beginning everytime I start something new. However this eats a lot of my time. While classes move on I see myself lagging behind.
