Thank you very much for a responsible reply. What do you think that what kind of maths should be prepared for it. As I also have to take my Teaching tests e.g. pst, jst and lecturer for Economics. Apart form them, I am also preparing for CSS. Further more, I have to take B.ed and masters exam in the coming month. A lot of burden and have many things to do at the same time. Please suggest me about these thinks to handle them. All things are connected to each other. Give me suggestion for them.
