I have done computer engineering. Now I want to take css exams 2014. My eye site is -1.75. Is this ok for css. I am also confused about subjects selection. If i opt for science subjects, phy, comp and stats which I learned during academic. but past papers of these subjects in css are quite difficult. I have not learned that much during my academic. From other subjects of css, I think to opt for accounting and auditing with which I dont have background, but I think that will be easy. I want to go for foreign service. which subjects I should choose, and how to start my preparation. I also want to have some useful info about different groups of css.
