GATE 2020 CS & IT Preparation: Graduate Aptitude Test in Engineering, GATE 2020 Exam is an online examination for admission to Post Graduate programs in engineering domain and PSU Recruitment. Computer Science and Information Technology (CS & IT) is one of the preferred branches in GATE exam along with Mechanical Engineering, Electronics and Communication Engineering, Electrical Engineering, Instrumentation and many others.
The GATE 2020 exam will be held on February 1-2 and February 8-9, 2020. Owing to a large number of applicants, the CSE GATE 2020 exam will be held in multiple sessions. The GATE 2020 results will be declared on March 16, 2020, by IIT Delhi, the exam conducting body.
We here bring the GATE 2020 CS & IT Syllabus, books to be referred for GATE CS & IT preparation and Guidance for preparing and scoring well in CSE GATE 2020 exam.

Preparation Plan for 4 Months
First of all, relax! There’s an ample time left to thoroughly prepare for the examination and crack. Secondly, make an examination preparation plan to properly divide the time. There are still 4-5 months left for the preparation.
- The technical section is considered the toughest of all the sections. Hence, Give this the maximum time. 3 months should be given to the technical section for its preparation and also for the practising of the questions.
- Engineering Mathematics and General aptitude are considered scoring. Hence, give 1 month for the preparation. There are many several contents available online for aptitude questions to be cracked by easy tricks.
- The last month must solely be given for the revision of the important topics marked during the initial preparation. This month must also be dedicated to the practising of the mock tests.
Proper preparation strategy, determination and focus required to Crack the GATE examination. Do not strain yourself till the last minute. We suggest the GATE aspirants be determined and diligently observe the tricks throughout the preparation period and prepare accordingly to achieve the goal to crack the exam.
