Nielit scientistB exam question paper pattern
National Institute of Electronics & Information Technology (NIELIT) recruits scientists from various branches every year, the selection process consists of written exam. The syllabus for this post was already given in my previous posts but here i am giving a flow chart of exam pattern which consists of both technical and non technical questions based on the syllabus.
Preparation Steps to Success in any competitive Exams
Now a days there is a more competition for any competitive exams.Here I am giving some important steps based on my experience to success in any competitive exams related to electronics like BSNL, IES, GATE, BARC, DRDO, ISRO, BHEL, BEL, GAIL, etc……..
Step1: First step is read the notification completely and if they mention any exam date in notification note down the exam date,If they didn’t mention the date then just assume that the exam will be held with in 2 month from the release of notification(now note down the expected/assumed exam date).
Step2: Now next step is to know the syllabus and exam pattern ,search the internet/website of company and take the printout of the syllabus.
Step3: Most important step is to find previous year question papers,Search internet or Buy previous papers books in a market or online.The previous papers are used to give an idea about the exam pattern and to know what type of questions are giving.
Step4: Now check the previous papers questions, are these questions are coming from syllabus or not.If any question is from outside of the syllabus then you just add that topic into syllabus.
Step5: Until Step4 we collect the sources to prepare for the exam.Now according to the exam date and based on your convenience you should prepare a preparation daily plan/Time table.
Step6: According to the Plan/Time table Start your preparation.Before reading any text book first check the previous questions concert to that subject/topic and observe what type of questions are giving, and which areas they covered most,so that its becomes easy to study and give more interest to study.

Gate 2018 all India exam preparation tips to Crack the exam
Now a days GATE is becoming more popular Because from the year 2012 onwards Most of the PSU’S recruiting people through GATE score and students showing interest on higher education like M.Tech/M.S are increasing every year in India. It is easy to crack GATE exam (I cracked GATE –EC 2012 and I was studied in NIT) if you follow these simple steps. I already posted the details about GATE in my previous posts you can check it to know more.
Why GATE 2018 exam?
Because GATE exam is important to do M.Tech/M.S in Top universities like IIT’S,NIT’S ….Not only that its very important to get jobs in PSU’S like NTPC,BHEL,BEL,HPCL….and also every year BARC is recruiting scientists through GATE score so many peoples have a question that how much score is needed to get all these things??? I will clear this doubt in my future posts,today my topic is how to prepare for GATE.
Steps to Crack GATE easily:
1. Syllabus: Collect syllabus from GATE website or you can download from here.
2. Research on your knowledge: Check the syllabus and know about yourself, i.e how much knowledge depth you have in those subjects because all these subjects you have already learnt in your graduation and make a list of subjects you are poor and on which subjects you are good.
3. Check In how many subjects you are poor and good from the list which you have prepared.If you are not clear with basic subjects, its better to join in any good coaching centers or learn subjects online from NPTEL ,MITOCW websites. Now a days some coaching centers offering online classes too so if you have interest you can check their websites for more information.
4. Previous papers & Making a short Notes: If you have some knowledge in subjects and you want to learn more in depth you can also take classes online from NPTEL and MIT those offering these courses for free and also follow at least two standard text books for each subject. Before studying any subject once check previous GATE papers and note down the areas on which questions are asked. First choose the subject which you are poor, while studying or learning focus more on those areas in which they are asking questions and note down the important points in a separate notes it will useful to refer before the exam.
5.Practice makes Man perfect: After studying one subject you need to practice previous questions of the respective subject from GATE and IES papers you can download these papers online or you buy it from market/online .
Why IES papers,sometimes in GATE exam they give direct one mark questions from these IES papers so you need to practice those papers also to differentiate your gate score from others.Practice more and more problems to crack gate easily.
6. Have a faith in your self: Without self motivation and self believe, no one in this world can achieve anything. Its tough to crack gate if you don’t have any plan or time table.Normally 3 to 4 months of serious study will be sufficient for the preparation so prepare your own time table now.
7.Test series: After completing your preparation take some online test series exams conducted by some institutes(like Gate Forum) that will helpful to know your preparation and also it gives confidence to the final GATE exam.

Best top GATE Coaching centers in IndiaHyderabadChennaiDelhi
After completion of my graduation I was thinking what to do next, at that time some one suggested me to take GATE exam for higher studies so,I decided to write GATE for that purpose I asked so many people who got success in previous GATE exams about the coaching centers i.e I almost done a small research on coaching centers. As per my survey most of the people suggest the below four coaching centers only so here I want to share my research with you.
1. ACE Academy: In every year thousands of people are taking coaching from this institute.This is the one of the best institute which succeeded in giving better coaching to GATE and it is located in Hyderabad.

Bharat electronics limited(BEL) is one of the largest electronic industry in India,every year they recruit maximum of 100 electronics engineers through GATE or a written test conducted by them and The written test will be held at Bangalore, Delhi, Mumbai, Kolkata and Guwahati centers only. So, Candidates should choose the test center nearest to their place of correspondence.
The written test is of objective type of both technical and General aptitude. In 2012 written exam they asked 150 questions with time constraint. In competitive exam time management is very important so,you should practice and prepare well to manage your exam time.
Mostly they asked basic theory questions and small problem based questions from the engineering subjects in technical sections,the technical paper is easy for a student who preparing or prepared for GATE/IES and while coming to the aptitude it’s little bit tough,and it will take more time to solve.
see more>>> ECE Technical Jobs
We are giving the expected syllabus based on previous exam,there is no exact syllabus given by BEL team.
Technical section: Follow the GATE and IES syllabus
Main Subjects: Analog electronics(concentrate more on Opamps, Amplifiers), Basics of electronics(concentrate more on FET,MOSFET), Digital electronics,Microprocessors, Logic families, Network theory, Antennas(More important don’t leave it), Transmission lines, Signals and systems(basics of signals, Laplace transform, ztransform) , Analog and digital communications, control systems, Engineering Mathematics ( in last exam they asked questions from Differential equations,integrations and matrices), 1or 2 questions from instrumentation.
Aptitude and reasoning: R.S.Agarwal book is sufficient.
Main Topics: Profit and loss, Simple interest and compound interest, time and work, problems on Ages, train problems, time and distance, pipes and cistern, Boats and streams so on………………
May be this year we are expecting questions for General awareness and General English also first of all you should practice technical thoroughly and then aptitude finally go for general awareness and English.
