Last 3 Months' Strategy for IES-2015 : Conventional Papers

 The strategy for conventional papers is almost similar to that of objective papers but first let's have a look at the structure of conventional papers. 


Structure of Conventional Papers:

Each conventional paper consists of 7 questions. The first question is compulsory and it contains sub-questions from all the subjects. Out of rest of the 6 questions, we have to attempt any 4 questions. Each of these question contains sub-questions from only one subject. 

It is not necessary to attempt questions serial wise but all parts of a question must be attempted continuously. 


Some Insights into the Subjects: 

Subjects like Network Theory, Signals and System, EDC, Digital Electronics, Control Systems etc. are easier in my opinion. They are purely numerical. Theoretical questions are seldom asked from these subjects except for EDC. Most of the numericals are based on a formula or a technique (e.g. in control systems many times questions have been in asked from Routh Horowitz Criterion ). 

We have already prepared these subjects in detail for GATE exam. Study material is easily available. These subjects can be prepared with least amount of effort. Hence we should prepare these subjects first and thoroughly.

Electromagnetic Theory is purely numerical subject but with difficult mathematical analysis.

Materials and components is largely a theoretical subjects. So is 'Microprocessor and Computer Engineering' if you are good with programming part. Many theoretical questions have been repeatedly asked from EDC. 

Microwave contains both theoretical and numerical questions. It has a large syllabus. It becomes bit tricky because of very difficult to remember formulae it contains. 

Analog Electronics and Communication Systems have large syllabus both theory-wise and numerical-wise.

Types of Questions being Asked:

Many of the questions are direct. They are based on a formula or a  technique or a simple concept. Sometimes a simple theoretical question (Difference between direct and indirect band gap semiconductor) is asked. The first question in both paper generally consist of such questions only. You have solved such questions in GATE exam and even in objective paper. These questions are abundantly covered in all coaching class notes, guides etc. Hence the preparation for these questions is not very challenging. 

The problem is with the rare kind of question which are generally not covered in coaching classes.

Many times few questions are repeated from a previous question paper. For example Question 3(b) in Paper 2 of 2014 is sequence generator problem. This question was also asked in 1983 question paper. UPSC can go that back!!! That is why it is absolutely necessary to solve all the previous year question papers. 

Prior to 2003 conventional question were also asked in GATE. Sometimes a similar question is asked from those. For example a question similar to 3(b) in Paper of 2014 was asked in 1990 paper of GATE. Two marker questions of recent GATE are also important for conventional point of view. 

Sometimes solved examples of standard books are also asked. In 2013 Paper-2 Q.3(b) has been directly asked from Morris Mano book.

A decent number of theoretical questions are asked every year so one should not commit the mistake of leaving theory.

Apart from all the above types of questions there will be some questions which are very tough. Since less than 3 months are remaining now hence it is prudent that we focus on what can be easily handled in such a short period of time.



Strategy :

In my earlier post I wrote that objective papers are about range of your knowledge. There is a bit change in the statement here. Subjective papers are about depth of your knowledge about the subject. Hence it is necessary that you should prepare 5 subjects in depth for each paper. However you should not completely neglect the sixth subject as the first question will contain a 5-marker from it.

1) First prepare easier subjects like networks, EDC (mentioned before) etc.
2) Solve all the previous year question papers. Ace Academy books are good for this purpose for two reasons : first, they have subjectwise and chapterwise classification of the problems. Second, they cover questions from 1980s i.e. more than 33 years of questions. 
3) Once you are done with IES papers, solve GATE papers. Pay more attention to conventional questions and 2-markers. 
Remember the purpose of solving IES and GATE problems is to be acquainted with diverse type of problems. Hence you can leave the repetitive questions.  
4) Keep reading the theory simultaneously. Analyzing the previous years paper would help in filtering important concepts from less important ones.
5) If time permits, try to solve examples from standard books. [I am asking to solve the examples at the last because of paucity of time. While solving examples don't waste time on the questions with which you are very well familiar. Try to look for more diverse problems.]
6)Keep analyzing and keep improvising.

When you are solving a numerical question, solve it till you reach the answer. Don't deceive yourself by thinking that you know the method and answer would be right. Because if you can't solve it here, how will you solve it under pressure in exam. [I committed the same mistake for 8085 programming. A 20-marker came. I thought I knew the logic but could not write the code.] We humans are animals of habit. What gets repeated also gets permanent. 

When solving problems in exam, write in a neat and clean manner. There is no limit on the space for answer. You can take supplementary copies. Remember that you have to solve all sub parts of a question together however questions can be attempted in any order. So solve the questions which are easiest first. 3 hours are more than sufficient for 5 questions so don't panic about time.

That's it for this post. If you have any comment /query /criticism/ suggestion kindly leave in the comment box. I will be more than happy. I will try to write about GS preparation in next post.

Last 3 months strategy for IES-2015 : Objective Papers.

I hope your preparation is going in full swing. IES-2015 is going to be organized from 12 June 2015 to 14 June 2015. I also hope that you have built very strong concepts till now. It's time to apply those concepts by solving as many problems as you can

The key to getting selected is to give proper attention to all 5 papers and not neglecting any of them as cut off is going to be very high. In this post I am going to discuss strategy for objective papers.


Preparation for Technical Part : Objective Papers

The nature of the exam has not changed since last few years. Most of the questions are repeated. In objective papers most of the questions are formula based. You will believe me more when you will be solving the question papers.

Objective papers test the range of your knowledge. Hence it is advisable that you do not leave any subject for objective papers' purpose. Even if you had not studied instrumental engineering in your B. Tech. you should try to have a basic understanding for the purpose of objective papers.

In objective papers we have to solve 120 questions in 2 hours that means one question per minute. Hence try to inculcate faster speed and accuracy while solving questions. Do not use calculator while solving objective problems as it is not allowed in the examination.

IES objective papers differ from GATE papers in two aspects. The questions in GATE are more conceptual while in IES they are more formula based. In GATE almost all the questions are numerical type but in IES lots of questions are theoretical. 

Resources Needed
1) Your class notes - Generally hand written class notes of various coaching institutes are considered good by the aspirants. They are available at various photocopy shops. You can also download them from here and here. Some of these class notes are really very good while some are not even legible. They cover large portion of the syllabus but not all. 

If you find anything is missing or is difficult to understand then you should refer to standard books, nptel courses, correspondence course etc on need basis

2) IES objective solved papers - Buy those papers which have subject-wise and chapter-wise classification of questions so that you can solve all question as soon as you finish a chapter.

3)GATE objective solved papers

Steps for preparation
1) For each subject prepare a formula sheet - If you had not already done it, then write whatever you feel important in that sheet.
2) Solve all the previous year question papers. You will realize that most questions are repeated with only change in numerical values. 
3) If you find any new concept or formula, add it into your formula sheet.
4) If any question is tough, tick mark it for solving again.
5) Also solve GATE papers . Do not forget to solve all three papers of GATE-2015. Concepts of 2 marker GATE questions are also useful for conventional papers. But priority should be given to IES papers.
6) Keep updating the formula sheet. While solving the papers you will come to know which formulae are more important. Revise the formula sheet regularly. 

Once you are done with all the previous year papers, solve some full syllabus test papers. Be time bound while solving. Use an OMR sheet to fill options. This give you confidence for the real examination.

My next post will be about conventional question papers.

Cut Off analysis of IES exam : How many marks you should be aiming to get selected in IES-2015?

The cut off for any exam depends on factors such as number of vacancies, difficulty level of the paper and level of competition. The last factor is increasing every year because of explosion in the number of engineering colleges. ECE is such a branch is which found in almost every college. Rise in the number of coaching centres has also added to the competition.

Let's have a graphical look at cut off marks for various categories -
IES ETE cut off GC
General Category

IES ETE cut off GC
OBC

IES ETE cut off SC
SC

ST Category


The following graph represents the number of final selections in ETE branch -
Number of finally selected students.


We can conclude the following things after looking at the above data -
1) The cut off for electronics has always shown a non decreasing trend for all categories.
2) Particularly general category cutoff is increasing by 20 to 30 marks every year irrespective of the number of vacancies.
3) The difference between general and reserved categories is also decreasing.
4) In the last 5 years cut off for ST has shown a whooping rise of 182 marks!!

My seniors in college used to consider ESE an easy examination. The nature of papers have not changed much during these five years. Only the level and quality of competition has rose and it will keep rising in the near future.

The purpose of this post is to set a target for yourself for ESE-2015. This year total number of vacancies is 475 for all branches. It means there are less than 100 vacancies for electronics (However we cannot be sure at this point of time.). Assuming the nature of paper remaining same, cut off will definitely rise. We can predict it to be around 670-680 marks. One should target 700+ marks to be in safe zone. For that one has to get 600+ marks in written exam. It seems tough but if one give proper attention to all five papers and do not neglect any of the papers he/she can achieve the goal.

In my next posts I will present analysis of last two years' conventional papers and a strategy to maximize your marks in the remaining time.
