You can prepare if you properly plan your preparation.
Subjects are excellent in which you are interested and have some background also.
Prepare compulsory subjects first.
Best of Luck

i want to start with english .. so any particular books for this subject .. i-e for new vocabulary .. idioms etc

You can use multiple books for this purpose e.g English grammer by Wrin Martin, Exploring the world of english

should we go through those books which fpsc has recommended ??

Yes. You can read FPSC recommended books, but almost all aspirants use helping books with reference or general books because it save time as well as we get idea to construct an overview of topic.
Helping books are good if their writing , language , grammar and critical analysis in standard mode and we can save time and also can get maximum marks.
