Yes! Congrats on passing your exam. It's always nice to show others that you know the material, but the real joy is in knowing that you really understand the concepts and can carry on insightful
interactions with others. Not to mention that your mind kicks in and starts getting creative and
asking neat questions and coming up with new ideas (most of which someone else has already done but the fun us in coming up with it yourself).
Keep those brain cells buzzing! You are apparently blessed with a bunch of them.
Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
