I could remember only 80 questions out of 100. If anyone who appeared in the test does have any more questions not included above, send them to me! The question order is jumbled, the questions of Subject Part wer en’t classified in subcategories in the actual test.
So, how was the test? Seemed a little difficult to me at very first. Some questions were knavish, many were irrelevant to Power Engineering and no doubt some were easy too! But overall test was satisfactory (to many) including the General Portion. If you can attempt ~40% questions right now, you’re expected to attempt 75%+ questions with proper preparation. More than 60% questions are numerical types and calculation based that’s why a non-programmable scientific calculator is allowed in the test ( The calculator is much helpful in the test, much more than you imagine, bring an original scientific calculator with natural display, download its user manual from its site and read the complete manual, the one/two hour(s) you spend on reading the calculator manual will help you save time and earn extra marks during the test ). I solved about 4-5 questions using advanced natural display calculator which I couldn’t have solved with a simple scientific calculator or if solved with simple scientific calculator would have taken me twice or thrice more time!
What to prepare for the test? Preparing irrelevant subject matter for years will have no practicable effect on your test results. Try to be fo cused, prepare well, and try to avoid far-flung rote learning. Here are the outline of the Test as supplied by PIEAS: The question paper is divided into two parts i.e. Part (A) and (B). There will be 50 questions in Part (A) and 50 Questions in Part (B). Part (A) is the general part to be attempted by all the candidates (except MBBS/Medical Sciences students) whereas Part (B) is the subject part having subject papers. Only the subject paper relevant to the candidate’s academic background may be attempted by the candidate. The candidate should mention the subject paper he/she is attempting by filling the appropriate section of the answer sheet. The maximum time allowed is 3 hours. Each question carries 3 marks and 1 mark will be deducted for a wrong answer.
A. General Part: i. It consists of three fields namely Mathematics, Physics and English. By: Muhammad Sarwar-10EL20

ii.
General Part must be attempted by all the candidates
iii.
General Part will have 50 questions in all. 20 from Mathematics & Physics respectively and 10 from English
a) Mathematics (Level F.Sc and B.Sc) Topics: Basic Calculus, Differential Equations, Complex Variables, Boolean Algebra, Vector Algebra, Matrices, Statistics b) Physics (Level F.Sc and B.Sc) c) English B. Subject Part: It consists of 50 question from Electrical/Electronics/Telecommunication in the following proportion:
Electrical/Electronics/Telecommunication RELATED TOPICS Basic Electrical Engineering, (Electric circuits, Electric and Magnetic Field Theory and applications, Digital Logic) Electronics, Electronic Circuits and Components Controls and Communications Systems Power (Machines, Distribution, Generation, Transmission, Protection, Power System Analysis, Power Electronics)
SHARE (Approx.) 45% 20% 15% 20%
General Part Preparation: Mathematics: Prepare F.Sc Part 1 maths: Ch. 1 to Ch. 7 (Skip Trigonometry & 8th chapter). Each chapter is equally important and keep in mind that Test is numerical based. Memorize formulas and work out with calculations. From F.Sc Part 2 Maths: Skip Ch. 5 and prepare remaining all 6 chapters (you may skip Ch. No. 6 too, but it’s better to prepare some basics of 6 th chapter). Pay special attention to Ch. 2 & 3. Though each chapter shares equal importance in test, one or two questions are included from each chapter roughly. Physics: Go through all the chapter of Physics F.Sc Part 1 and Part 2 books. Learn all the formulas and be good with calculations. Last 3,4 chapters of 2 nd year Physics are important. English: English has nothing to prepare, because no specified course can be allotted for English preparation. This is the first portion of the General test consisting of 10 questions. 1 st two are from comprehension, so they are easy. Next 3-4 are synonyms & antonyms, they’re easy too but confusing, tick them carefully. By: Muhammad Sarwar-10EL20

And remaining questions are correct form of verbs, prepositions or correction of grammar mistakes.
Subject Preparation: Basic Electrical Engineering: Revise Circuit Analysis I & II from David Irwin’s book or any other Basic Circuit Analysis book (1st order & 2nd order circuits are important). Review EMT from William H. Hayt’s Book or Alexander Sadiko’s. Learn all basic equations (i.e. Maxwell’s, Poisson, Laplace, Ampere, Green/St okes Theorems etc.). Have a basic review of DLD book by Thomas L. Floyd . Pay special attention to combinational logic circuits (They’re important). Have an insight of sequential logic. You may skip K-maps and other lengthy portions. Electronics, Electronic Circuits and Components: For this portion, prepare thoroughly Electronic Circuit & Devices by Robert T. Paynter or Thomas Floyd’s Electronic Devices. FET, JFET and MOSFET’s components, circuits, biasing and analysis is REALLY important. Learn them by heart (in fact brain :P). Controls and Communications Systems: For control systems, review Control System by Norman S. Nice . ( Samarajit Ghosh’s book is not up to standard). Revise basics of Open loop & Feedback Control systems. Stable & Un-Stable system conditions, poles-zeros plots, bode plots, frequency response, Phase margin, gain margin, root locus and all basic relevant topics. Communication Systems: (Advance topics from this portion are asked in test) Prepare Laplace & Fourier transforms (important). Harmonics, AM & FM modulation techniques, Slew rate, Fourier magnitude & phase plots, filters (IIR & FIR). You may refer to Modern Digital & Analog Communication Systems by B. P. Lathi. Also review topics from Signal & Systems and DSP. Prepare basics (i.e. LTI systems, signals & their properties, convolution, Fourier series & transform plots of a signal etc.)
Power: Prepare AC & DC machines from chapman. Revise selective topics of Power Engineering from Principals of Power Systems by V.K Mehta. Power calculations are very important (i.e. finding base values, Impedances, Real & Reactive power flowing through a circuit, capacitance & inductance values). Revise Power generation too (it’s important). Also revise Power Electronics topics

especially for SCR, IGBT, MOSFET, BJT, DIODES, TRIACS & DIACS; their properties, construction, circuits & applications. This is the complete course outline for M.S fellowship test. But you must prepare more than that mentioned above in order to succeed. By carefully observing the 2014 test questions, you may find out the exact (But up to a limited accuracy) topics to prepare for a specific subject for coming year’s test. For example from Circuit Analysis, questions of Series Parallel combination of Resistors, 1 st order & 2nd order circuits, Maximum Power transfer theorem, Basic Current/Voltage division, KCL, KVL are much important because questions related to these topics have been found in Fellowship tests. For instance, at least 3 questions were related to FET, JFET, & MOSFET as listed in above questions, so this is most important topic! Same is true for Op-Amp. Carefully read the sample paper; also search Internet for past papers for PIEAS B.S and M.S fellowship tests (2010, 2011, 2012 & 2013; 2014 is given above). At least 3-4 questions (or may more) are from past papers. And many more or related to past paper questions with just small changes in values etc.!
How much time should you allot for test preparation? The answer to this question is quite important for an aspirant candidate to succeed. The time you set aside for your test preparation depends on a number of factors; you have to ask a couple of questions to yourself:
What is you previous Knowledge Level about the subject(s)?
Are you starting from scratch?
Do you plan to revise only or to read the topics thoroughly?
What is your intelligence level?
How much are you eager to learn?
What is your Method of Revision?
So, scrutinize each subject and its sub-topics according to Previous Knowledge, Type of Revision etc. and you may be able to allocate specific time for each subject. Manage your time well and you may be able to revise a lot of material in shorter time span! :) For just to take an example, I completed my revision in 4-5 days from 04 June, 2014 to 08 June, 2014. I revised only F.Sc Maths and Physics books, because I had left with no time for Subject Preparation (as 8 th semester’s

finals started from 10 th June). Then I got one and half day more after 2 nd paper of finals. I again reviewed Maths & Physics one time and looked upon some topics from engineering subjects. That was all of my preparations! Attempting a MCQs based test is itself an art. Mastering that art with a proper commingle of preparation will get you through any test. You’ve 3 hours and 100 MCQs; spend each second of available time wisely. In the first round, attempt only easiest question which you can solve in less than 30 seconds. Then in the next round try moderate questions. And in the last, attack the Hard questions, answer those which you can easily solve, don’t spend a lot of time on a single questions. Use your Brain & Calculator collectively. While attempting questions in the test, beware of the –ve marking, don’t attempt a question unless you’re completely sure for the correct answer. Never answer a question by mere random guessing. If you don’t know an answer to question, use educated guesses that may increase your chance for guessing a correct answer. Read the question and its answer choices carefully, now relate each answer choice to the question and find the chances for this choice to be a correct answer. Use the techniques of reverse solving, inference from other option, use analogies and make a decision that the choice being considered can be an answer or not. Similarly, work out all the option choices and each time roll out the choice which has no (or relatively lesser) chance to be a correct answer and this way you may increase the probability for guessing a correct answer. If 4 multiple choices are given for a question then you have 25% (1/4) probability of guessing a correct answer randomly. If you eliminate one choice then you’ve 33% chance and if you eliminate two answer choices your correct guessing chance rises up to 50% and so on. I answered 98 questions. About 15 of them were educated guesses, 70+ were correct (according to me), so I expect to get 220+ marks out of 300. I think 200 marks are enough for a candidate to be shortlisted for the interview!
