Yes preparation of CSS can be done only within 2 month. It is not a big deal, shocked! no need to be shocked! :p yes you can do it provided you are English lecturer in a well-reputed educational institutions; and the subjects you mentioned have been studied by you in your academic career and have grip over them.
