@Roshnain & Waqar,,,,,
Can we start combine preparation for English Essay?????
We should start by considering a major area like economy, education, or terrorism etc and then every week one topic from past papers should be selected; we all will research for the whole week about the data relevant to the topic & will write on the mentioned topic of the week. After writing the whole essay we will send them to each other for checking (especially grammar related mistakes, relevancy & structure of essay). As maths & physics are expected to fetch good marks. Focusing two English papers for all three of us is inevitable. Practicing & highlighting the mistakes of each other is the only way, in my opinion, through which we can pass the two papers.

That really is strange then. How comes there are typos in two consecutive papers? The problem with Maths is that a single typo can make the solution impossible and one not only will lose 10 marks but precious time as well.

Am sister bro.

Thats a good plan but i have not started working on essay yet. But yes, we can work together on that.

@Roshnain
From the very first day we should work on essay. As all the papers on one side & essay is on the other side. One of my friends who is a CSP now, told me that essay & c.affairs should be carried on with an optional subject and a compulsory subject on daily basis. If we dedicate Saturday & Sunday for essay preparation it would be a pertinent strategy in my opinion.
Do u know any best professor in Peshawar region for essay.???

I do not know any teacher. I ll be preparing on my own. But i agree that dedicated efforts are required. So lets see what Waqar has in mind.

there is a simple technique for essay, don't worry. and I am waqaS not waqaR . in the meantime check outlines of Tashfeen Alam on the forum. He has never failed an essay! I learned from him last year. but he is on the forum and he is helping aspirants.

ok guys. i presume it is your first attempt? so first of all calm down, do not hasten things up. have you covered all your optionals? have you covered both math and physics? it is good that you want to jump off to essay but have you considered where you are and how much there is left? are you managing your time properly? aren't you wasting time on facebook? have you turned off your cell phone for good? are you following a particular routine? are you covering more of the syllabus every next day? is your study stamina increasing? or is it that you hit the bed every night and "promise" yourself that "i will do it tomorrow"?

also both of you state your third optional.
mine is economics.

@engrsarakhan. forgive me but are you sis or bro?

@Waqas,,,,,
No its my second attempt. My first attempt was with almost 20% preparation as i was also enrolled my MS as well. I have covered paper2 of physics. Working on Mechanics (the most difficult & pathetic part of maths). My other two optional papers are pustho & journalism. What are your qualifications.? Economics is quite diverted option. Have u gone through pustho syllabus, i attempted the paper just with 7 days preparation. Its course is v. short. With physics & maths, i think one should opt for small syllabi courses. As the two are already time consuming.
Brother, as u r working on Diff Eqs, have u searched out from where the question (x^2+1)y''+xy'-y=0 came in CE-2014 paper.
What is the name of this method. I have not seen any 2nd order problem in which the co-efficient of y'' is other than x^2 or a constant.
