English Essay

The most vital part here is Outline preparation. Once you have developed a strong outline, lets say with around 20 points, it shouldn't be hard for you to write 3000 words on it. Write and develop a few outlines on hot topics (Pakistan's economic issues, women, islam as a religion, global warming, politics/democracy) and ensure you prepare only a maximum of 5 outlines. With each outline, prepare appropriate quotes and events. There is no need to write an essay however if you are not confident about your speed, you may practice 1/2 essays. All this shouldn't take more than 2 days. Internet should be your best friend

English Precis & Composition

This is probably the easiest paper. Just prepare antonyms, synonyms, proverbs and idioms from any book of your choice. 

You don't need to prepare composition as you have already done it extensively in O levels. Trust me, in CSS its much easier than O levels

As far as precis is concerned, it is quite easy, contrary to what people say. You have to summarize in easy words in 1/3 the word count. Once again consult any book for solved precis of past papers which should give you an idea and you are all set to go

For short notes, once again the quotes and events are your gateway to success. You do not need to prepare for this because writing 300 words shouldn't be difficult for you especially when coupled with quotes and events which alone would take up at least 100 words

This paper therefore shouldn't take more than 2 days to prepare too.

EDS

The most scoring subject which you should ace.

All you need to do is read Everyday Science book of Kashmiri. 1 reading shouldn't take more than 2 days. Revise at least 3-4 times whenever you feel like. Also get solved papers of last 10 years and you are all set to go. No need to do anything else
