CRACK ISRO : ECE
Way to crack ISRO exam SCIENTISTS/ENGINEERS 'SC' ELECTRONICS
this exam is conducted every year during April/may , to be honest
syllabus is not limited, being an electronics & communication engineer i
would like to share some valuable info regarding this exam here, some may feel
that this exam is very much similar to GATE, perhaps extra effort is needed.
since syllabus is not limited to those 9 subjects, in addition you must read at
least 5 more subjects, there will be 80 multiple choice questions, theory or
problems no matter,every question carries equal marks i.e (3) and each
wrong ans carries -1 time is limited i.e 90minutes only and you must
effectively utilize it to solve max i.e at least around 55 questions, of course
achieving it is not an easy task, here are some tips u may follow to clear
written test (first elimination process)
1) Plan to perfection: planning is the key, not many would like to put some extra effort for this exam particularly when they are busy in preparing for GATE, remember u will get at least 2-3 months of time for preparation after GATE, (beat the iron when it is hot) this is the crucial time, or time to cash in since you will be in touch with those 9 subjects to be specific ( maths, edc, analog circuits,digital circuits, networks, emtl, control system, communication, signals & systems) so don't relax, read them again thoroughly, then go for those 5 new subjects. Also it will be good if you follow a particular sequence for preparation i.e there will be some similarity in some subjects so club them together and read, for better understanding try to analyze everything from basics

2) Forcast & prediction : there must
be direction for your preparation, solidity and only way to gain it is to refer
to previous papers (2006-2013) try to solve them on your own initially as a
test, and check whether are you able to solve at least 55 with in 90
minutes, later find solutions for all questions (80*6), 480 bits. mostly some
questions are repeated (keep a keen eye on those bits) also current year
concepts need not be repeated in next year's paper, try to make a note on what
kind of concepts are covered in each paper asses yourself whether you got
those concepts or not, based on those previous papers you must be in position
to predict what kind of concepts may come or repeat in next year's paper, key
is you should not waste your time in solving those repeated question again,
mostly those questions are repeated with out change of data, options too. try
to dig front & back of those concepts and learn it's surrounding concepts
too.
eg; 1) if a question is given on which codes have high coding gain? then you must cover basics of all codes like ( linear block codes, turbo codes, convolution codes, BCH codes , RS codes, cyclic codes , LDPC codes) their basic features like (minimum distance (dmin), message bits of (n,k), error correction capability (t) , redundant bits (n-k) , coding ratio (k/n) coding gain )
3) Implement it effectively : Solving those papers may not be tough for those, who are not yet done with their studies but it will be a tedious job for those who are out of touch, you may use internet(mobile) to find out solutions of some questions but mostly it will be effective if two or three people in same mission working out on those problems since it induces competitive spirit also helps to have cross-correlation,it helps you to check your status, self preparation is needed but it sometimes makes you feel lazy since no one to direct i.e
auto-correlation always gives you a peak, no matter whether you are prepared or under-prepared or may mislead you , so its better if you compare your preparation status with others if possible take a short test (oral test) on your own with your friend or mission partner
4) Five A's to be followed : you must be Alert, Agile, Accurate, Aggressive , Aware of what you are going to do, after all being human beings we can't remember all things, whatever we read or learn so constant refreshing is needed, read all concepts repeatedly at the same time try to learn 2 or 3 new concepts daily, invade your subjects in an innovative manner such that you may find news ways to solve same old problems in short span of time, remember there will be at least 35 theory bits in each paper so try to solve them since such bits need not require second thought, time saving is key to solve time consuming problems later.
