Useful & Important Preparation Tips for NIELIT Scientist B 2020 Exam

The National Institute of Electronics & Information Technology or NIELIT Scientist B 2020 exam is a specialised recruitment government examination. It allows selected candidates to work in the prestigious Ministry of Electronics and Information technology department.


The Scientist B hiring process consists of a Written Examination [85% weightage] along with Interview [15%] and only those few who clear the former are called for the latter. This article aims to present the best NIELIT Scientist B preparation tips along with some interesting insights into the exam.


NIELIT Scientist B Syllabus and Exam Pattern

The NIELIT Scientist B syllabus comprises of two sections namely Generic and Technical as stated in the following table. It is an objective-MCQ based test with 120 questions to be complete in 3 hours. Each question carries 1 mark, however, there is a negative marking of -0.25 for every incorrect answer.


Section Topics Weightage Questions
Section A Generic Quantitative and Qualitative abilities, Logical Reasoning, Analytical Reasoning Capabilities, General Aptitude 35% 42
Section B Technical [Computer Science] Probability, Statistics and Combinatorics, Digital Logic, Computer Organization and Architecture, Electrical Engineering, Analog and Digital Communication, Programming and Data Structures, Algorithms, Compiler Design, Operating System, Databases, Information Systems and Software Engineering, Computer Networks, Web Technologies, Cyber Security and Emerging Technologies, Cloud Technology 65% 78
Total 120


NIELIT Scientist B Preparation Tips: Section A Generic

  • There are 42 questions in this section. As per the last year, Quantitative and Qualitative abilities had 19 questions, Logical Reasoning stood at 15 questions and Verbal Reasoning consisted of only 2 questions. Both Logical Reasoning and Verbal Reasoning were of easy difficulty with the rest on moderate.


  • Data Interpretation is a scoring section which had a weightage of 6 questions last time out. You will be presented with a table/pie chart/graph/line chart and a set of information and instructions on how to interpret it. Normally, you will be asked to calculate ratios like profit percentage and like. Exploring mock tests will give you a fair idea.


  • Questions on reasoning follow a set pattern: instructions/directions, problems statement and choices. Many a time, the directions and problem statement combine multiple topics and present a situation in a convoluted manner. Try to visualise, imagine and draw the possible situations mentioned in question if you are stuck at it. Consider the possible alternatives, eliminate extreme and improbable choices, go over the selected option once again if you don’t get right at first. Rephrase the problem statement, isolate the different elements and try to see the pattern in them.

NIELIT Scientist B Preparation Tips: Section A Technical [Computer Science]

  • In this section, the syllabus is quite vast. Going by the last year trend, Computer networks accounted for 11 questions, DBMS for 9, Information Systems and Software Engineering for 7 Data Structures for 8 and Algorithm for 10 questions. The difficulty level of all of the above topics was easy-moderate. Topics like Discrete Mathematics, Data Structures and Algorithms, Operating Structures are also crucial.


  • In addition to NIELIT Scientist B study material, it will also be of aid if you refer to GATE material as well. GATE questions are at par with the standard of this exam and will give you a solid understanding of questions.


  • This section is much about practice as it is about memory. Divide your NIELIT Scientist B preparation into two phases, In the first phase, finish up the basic portions such as probability, operating system, computer networks and like. Mathematical logic is a vital topic as it is widely used in various other topics. Advanced segments like programming and data structures, algorithms, electrical engineering, digital and analog communication then, will fit to be covered.


  • There is a significant portion of theoretical information in the NIELIT Scientist B syllabus. To make sure you are well-versed with it during your preparation, use creative learning techniques like diagrams, flow charts, puzzles, charts etc. to help you easily remember and recall. This also helps with formula learning and memorization. Further, topics like cybersecurity, cloud technology, etc. relatively and you may be tested on recent developments on this front.


  • Probability, Statistics and Combinatorics are one of the tricky sections on the NIELIT Scientist B 2020 exam. Therefore, you must be thorough with diverse as well as straightforward and simple questions to get the most out of it. Refer to the best NIELIT Scientist B study material to heighten your chances.


  • Combine short topics –based tests with half-length and full-length tests. This gives you a fair idea of where you stand and what challenges you might be facing on the actual exam. The latest NIELIT Scientist B study material will have such tests in abundance.


  • NIELIT Scientist B study material: Multiple Choice Questions for GATE / PSUs by Made Easy Publications, MCQs On Computer by Alok Kumar [Upkar Publications], Analog and Digital Communication by Ashirwad’s Publications, Computer Awareness by Mini Goyal and Shweta Rani by Arihant Publications, MCQs in Computer Science Books for NIELIT Scientist B and Scientific-Technical Assistant by McGraw-Hill Publications.


NIELIT Scientist B Preparation: Key Takeaways

  • Time Management: You will be faced with 120 questions in 180 minutes which comes out to 90 seconds per question. While Section A may not be time-intensive, Section B is bound to be a stretch. Our suggestion is to divide the time into 5 minutes of Pre-Reading, 57 minutes for Section A, 107 minutes for Section B and 10 minutes for Revision. This is only an outline and you can make changes as per your suitability.


  • Revision: In the last 10 -15 minutes, go through the question paper once again, revisiting the tough ones and their calculations, questions that you might have left and anything else like silly mistakes, marking errors and much more. You can save essential 3-4 marks.


  • Temperament: Keep a composed and calm attitude, don’t panic at any phase during preparation or in the exam.
