GATE 2023 Marking Scheme is different for different papers. Each correct answer is allotted 1 mark or 2 marks. While there is no negative marking for MSQs or NAT, incorrect MCQs leads to a deduction in marks.

  • For MSQs: Total marks for 1 mark MSQs + Total marks for 2 marks MSQs

Ques. Why many GATE toppers leave PSU and join NITIE instead of IITs?

● Top Answer By Aditi Gupta on 01 Apr 22

Many GATE toppers leave PSU and join NITIE, instead of IITs, because it offers better placements. Usually, students with good scores join  ONGC, NTPC, BHEL, IOCL, and others. Despite the good salary, the PSU jobs can get monotonous after a few years. So, the top rankers start looking for better career options. If they wish to do an MBA, they need to prepare for CAT. Some do prepare for CAT, but many join NITIE as it is an easier option. NITIE takes admission through GATE and the GATE score is valid for 3 years. So, they can easily get admission based on their GATE score.  Also, the institute has a great placement record. During NITIE Mumbai placement 2022, the average CTC offered was INR 25.41 LPA.  ...Read more

Ques. What should be the proper strategy to excel in both GATE and ESE simultaneously?

● Top Answer By Subham Patra on 15 Jul 22

Here are some strategies that can help you prepare for GATE and ESE simultaneously. Compare the syllabus of GATE and ESE. Go through the previous years' questions of both. The technical portion of both examinations overlaps a lot. The major difference is question patterns and styles. Different types of questions are asked on the same topics. GATE tests aptitude for solving technical questions. While ESE puts more emphasis on technical details.  Figure out which subjects contribute more to which examinations.  If you have less time, start with GATE preparation. The topics can be covered easily and in less time. Once you are through GATE preparation, you can solve ESE questions without much difficulty.  Focus on GATE and ESE preparations only.  First, go through the syllabus thoroughly. Once you are done with the syllabus, go through your notes and solve previous years' questions. Solve test series, and review hard questions. Analyze the tests you give and work on your mistakes. ...Read more
