ESSAY PART 2- HOW I DID IT.

Hey Guys!

Essay is definitely the most subjective element of the entire process, far more subjective than the interview. Although I do not consider myself qualified enough to talk on this, I thought I should share whatever I did. I scored 80/200 in my first attempt and 125/250 in my second. Last year I had written on working women.  We had a chapter on Gender psychology in my optional and my mom and every other relative is a working woman, so I had good content on the topic and I thought I wrote well. But even then, I ended up getting mediocre marks. On the other hand, I wrote a pretty ordinary piece according to my own standards and had barely finished within time but ended up getting great marks. I have no clue as to how to explain this.

1)    I do not have great command over English. I can write grammatically correct plain English but with no frills. You need not be a Shakespeare to score good marks in essay!

2)    There is no need to prepare separately for essay as far as the content part is considered. Your preparation for mains will suffice for essay from content point of view

3)    I did not prepare on any topics in advance

4)     I did not use any quotes in the entire essay. You should if you can. Try making a list of quotable quotes from stuff you come across while preparing

5)    Practice at least 5 essays.  Get them peer reviewed. Try finding an English teacher/prof around and take his/her inputs.

6)    Coaching: coaching for essay is not really useful. I joined Ramaswamy and his inputs were useless. The only good thing was unlike other coachings which give a lot of Gyan and conduct only a couple of tests, he conducted 7/8 tests. So luckily what happened was that I was able to utilize introduction of one of the essays as it is in my mains.

7)    Introduction is the MOST IMPORTANT PART. Spend atleast 15-20 minutes thinking about  it.,

8)    Another 15-20 minutes should be devoted to conclusion which should be equally powerful

9)    In the main body, organization of thoughts is the most crucial thing. The essay should flow like a river as they say. Try covering as many aspects as possible – historical, social, economic, scientific or any other dimension that comes to your mind.

10) Length: Keep it moderate. It should be neither too long or nor too short. I do not remember how many pages I wrote but I devoted 2 hours for writing and 1 hour for brainstorming the content, organizing it and thinking of innovative introduction and a befitting conclusion. Roughly 1500-1700 words should be OK.

11) This time there might be two essays so manage time and word limit  accordingly

12) Essay remains a poor cousin of other subjects when it comes to preparation. Please do not commit this mistake! Last time what happened was that I wrote only 1 essay and that too I showed to only 1 person who praised it a lot and hence I did not feel the need to write more and hence could nt improve. Write at least 5 essays.

13) Long term : start blogging

14) You can also make a list of proverbs, idioms and phrases

15) CHOOSING THE TOPIC: please do not have any preconceived notions that a particular type of topic fetch more marks. The only criteria for selection should be availability of content!!!

16) In the end, pray to god! Because even after  doing all this results may/may not be commensurate the efforts made J


STRUCTURE OF THE ESSAY

1)      FIRST PARA: dhamakedaar bomb.  Write something very catchy which invites the reader to read what lies ahead
2)     Second: define the topic. Eg. This year I wrote on “Science  and Technology is the panacea for the growth  and security  of the Nation”. So go about explaining what is science, technology, ‘growth’ etc. I remember mentioning growth is just not GDP rise but includes social dimensions as well.
3)      Third: what follows/ major issues to be covered. Tell the reader what lies ahead
4)       Main body
5)      Pre conclusion summary: try to recapitulate all the points that have been stated earlier.
6)      Dhamakedaar Optimistic conclusion: give suggestions/constructive solutions. Don’t paint a gloomy picture.

HOW TO CRACK GATE AND OTHER PSU EXAMS(CHEMICAL)
Hey!

GATE has now become important as some 4/5 PSUs are recruiting through it. It should require preparation for about 3/4 months to crack this exam. I scored a rank of 36 in 2013 with 67/100 marks. In general category one has to get below AIR 60 to be really sure of selection.


        From 2013, GATE was made online. Many of the answers are now required to be filed in numerically using the keyboard (ie they are not of the multiple choice types) So, one has to be thorough with the concepts. Yes! CONCEPTS hold the key as the questions are generally easy but conceptual. Accuracy, of course has become very important.

Regarding chemical engineering courses, all of them are important and must be thoroughly prepared.  BUT, it is very important to have an idea about the pattern of questions being asked. MOST IMPORTANT part of your preparation shall be solving the previous year GATE question papers (say last 20 years) available on www.unitoperation.com. Analyze the pattern and focus on areas where questions are being asked regularly. Every year they tend to ask similar questions from same areas. For example, there shall always be some questions on ‘drying’.


The 15 marks of English and mental ability should not require any special preparation as such. In fact, this area is quite scoring.

Questions from the 15 mark section of engineering mathematics are usually very easy. But due to the length/coverage of the syllabus, people tend to go unprepared. DONT DO this mistake. I found GATE maths book by ‘MADE EASY’ very suitable in this regard.

Thankfully, many of the chemical engg. courses are now available online at www.nptel.iitm.ac.in (NPTEL). Make full use of this resource as they have covered the courses very concisely

GENERAL GUIDELINES
·       Practice practice practice!!! Giving tests in exam like situations always helps
·       Coaching: thankfully, there are not many coaching institutes offering coaching in chemical engg. Coaching is NOT required as such if you can follow a disciplined approach. I have heard of this institute called Vaani (Hyderabad) which offers test series (and coaching also). Joining a test series should be beneficial as it gives momentum to your preparation
·       Be VERY THOROUGH with the important topics I have listed below
·       Do NOT leave any topic untouched while preparation. Try to cover the entire syllabus as sometimes a very easy question might be asked from the topic you left. This is specially the case with engineering mathematics portion
·       They are going to test your basic concepts especially in the one markers. So, have a good read of the theoretical portion of the textbooks Ex. Internal energy is a  state function/path function ? (2013).

CAUTION: LIST OF IMPORTANT TOPICS IS NOT EXHAUSTIVE!!!
