go to "Edit my profile" and change your profile pic :)))

how do you change you profile picture

Read more at once and then type!!!

My tip to improve your typing speed are:
first, keep the record of your mistakes you do while typing and try to rectify it, more accuracy means more typing speed.
Second, whatever you are typing, try to read more words at once this trick is also very handful to type at fast speeds.
Third, never look down on the keyboard while typing.
Fourth, keep practising - make typing a habit, type at least 20 minutes everyday.
