The Graduate Aptitude Test in Engineering (GATE) is one of the reputed technical exams in India. Every year 7 Indian Institutes of Technology (IITs) and the Indian Institute of Science IISc conduct exams that lead to admission to M.E, M.Tech, Ph.D., and other PSUs. It consists of 100 marks paper which consists of 65 questions. It is being conducted once a year and the eligibility criteria is a 3rd-year student and above.

Today is the world of modern technologies like Artificial Intelligence, Data Science, Information Security, and Machine Learning. As the demand for engineers having these relevant skills is increasing, most of the students or working professionals who completed their B.Tech in non-CS branches want to pursue M.Tech from top IITs, NITs, and IIITs in India and secure their careers in these fields. It is very much possible that a student from non-CS branches can crack GATE CSE with a good rank with sheer effort and dedicated study for one year. There are tons of non-CSE students who cracked the GATE CS exam in the last few years and most of them have completed their M.Tech and now working in top MNCs like Google, Amazon, Apple, CISCO, etc.

GATE CSE Preparation Strategy for Non-CSE students


In this blog, we are going to cover how being from non-CS/IT branches, one can crack the GATE Computer Science exam. Also, we will cover how to start and from where you can learn important strategies. Let’s discuss them one by one.

Basic Steps for GATE Preparation

The first priority is to know the GATE syllabus. GATE is tough and its preparation takes time but if you’re someone who’s hard-working and has a proper planning strategy, you can crack it in one go. In Computer Science, there are generally ten core subjects:

You can also refer to:

  1. You will encounter lots of new terms in CS subjects. As you progress in your preparation, maintain a separate notebook for these new keywords. CSE students are already studying these keywords right from their B. Tech and are familiar with these words.
  2. The second most important thing is to know where to prepare. Visit GATE CS References to get a complete idea about standard textbooks and online references to follow during preparation.
  3. The third most important thing is to know the weightage of subjects in order to know their priority.
  4. One can start preparation with the high-weightage subjects. The following table is an average marks distribution for the last three to four years.


Marks Distribution

Data Structures and Algorithms15-20 Marks
Mathematics and Aptitude28-30 Marks
TOC and Compiler Design13-18 Marks
DBMS6-8 Marks
Operating Systems7-10 Marks
Computer Organization7-10 Marks
Computer Networks6-8 Marks
Digital Logic Design4-6 Marks

The non-CSE GATE aspirants who are willing to write the GATE 2023 exam in CSE can be broadly categorized into three categories:

  • Category 1: ECE
  • Category 2: EE, EIE, and IN
  • Category 3: Mechanical, Civil, Production, and other branches

Being from non-CS and learning Computer Science subjects is challenging but can be done easily with proper execution and planning. CS is generally abbreviated as Common Sense. Yes, with basic logic in Mathematics, Aptitude, and Programming, GATE CSE can be easily cracked. For that, a proper strategy for the next eight to twelve months is very much important. The three non-CS categories above-mentioned must have different strategies for preparing the subjects. 

Tips for the GATE Preparation:

  • DSA and C Programming- One should start with C programming followed by Data Structures and Algorithms as it has the highest weightage. For all three categories, students should focus on this subject first and give a dedicated effort. For placements also DSA and programming knowledge is mandatory. Every non-CSE student first honors the programming skills, especially in C. 
  • Discrete Mathematics- It is completely a new subject for all three categories. Discrete Mathematics is the heart of Computer Science. It has good weightage in GATE. Prepare this subject parallelly with DSA and C Programming. It has lots of applications in all the core CS subjects. 
  • Theory Of Computation and Compiler Design- These subjects are also new for these three categories. So, after completing DSA, dedicated study and proper practice are needed for these two subjects. The order should be TOC followed by Compilers. The compiler is completely related to TOC and hence it is the pre-requisite for Compiler Design.
  • Database Management System- Similar to DSA, Data Base and SQL are very important for every CS engineer. It is also an easy-to-score subject and has good weightage in GATE. 
  • Operating System- It is also important and an easy-to-score subject. OS will be a new subject for all the categories. A lot of new concepts and terms are there to memorize. For example, Contiguous memory, Pre-empt, etc. So, make a proper list of the keywords as non-CS students are not acquainted with these words. 
  • Digital Logic Design- Students who are in category 3, have to study Digital Logic before going to “Computer Organization and Computer Networks.” Category 1 and 2 students already studied DLD in their B. Tech curriculum. So, they can go with any combination as per your choice.
    Refer to Digital Logic Design.
  • Computer Networks- It will be an easy subject for Category 1 students because they have already covered “Computer Communication” in their B. Tech. Category 2 and 3 students have to put more effort into this subject. It is a vast subject and needs nearly twenty to thirty days to complete. During placements, top MNCs prefer to ask questions from networking. 
  • Computer Organization- It is the toughest subject in GATE CSE. But average marks can be easily scored from topics like Cache Memory, Pipeline, and Addressing Modes. 
  • Mathematics and Aptitude- For General Mathematics and Aptitude, Previous Year Gate CSE/IT papers with solutions of all the branches for the last 20 years and test series are more than enough. They have a weightage of around 15 marks for Aptitude and 3 to 4 marks for “Engineering Mathematics” from topics like Calculus, Linear Algebra, and Probability. Students generally don’t focus on these portions and prepare at the end. These two subjects will boost your rank as they are easy to score and have good weightage.
