Ans. 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, 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 the NITIE Mumbai placement in 2022, the average CTC offered was INR 25.41 LPA. The video below will convince you further to join NITIE Mumbai Overall, its the excellent opportunities offered by NITIE that makes mant GATE toppers leave PSU and join NITIE Read more
Ans. 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
Ans. GATE consists mostly of numerical questions. It tests the aptitude for solving questions in less time. BITS HD papers have 10-15 numerical questions usually. The numerical questions aren’t on the same level as GATE and are just formula-based problems. Usually, around 80-90% of BITS HD questions are theory oriented. You need to have a good grasp of your engineering subjects to score well in BITS HD. The questions can come from anywhere in the syllabus. BITS HD usually consists - 15 Mathematics questions (difficulty usually higher than GATE) 15 general English questions 70 Engineering discipline questions Also, note that BITS take admission based on GATE scores as well.

Ans. The required GATE rank depends upon various parameters like The engineering branch Company (PSU) Number of vacancies for the stream People who are graduating in 3-4 years are lucky as both IOCL and ONGC are planning to recruit in bulk because of massive retirements in both the companies. The mechanical and chemical branches are expected to have the most vacancies. Candidates will be called in a 1:5 ratio and thus, interviews will be the major determining factor of your selection. If you are unable to showcase your knowledge and talent during the interview, even a single-digit rank cannot guarantee your admission. A minimum of 40% marks are required to pass the interview. So if you get a call for the interview, don’t let your rank discourage you or even make you overconfident. Read more

Ans. IIT Roorkee admission 2023 hasn’t been wrapped up yet, hence its GATE cutoff too hasn’t been released as of now. M.Tech admission process of IIT Roorkee is conducted on the basis of the GATE cutoff, and all the candidates applying for admission into the M.Tech course under the non-sponsored category will be required to clear the cutoff for admission. The cutoff scores for M.Tech admission at IIT Roorkee for 2022 and 2021 have not been disclosed by the admission authority. Let’s consider GATE 2020 cutoff for a slight idea. Category GATE 2020 Cutoff General 77.1 EWS 79.1 OBC 72.32 SC 58.62 ST 61.33 Read more
Ans. First of all, admission to the IIT Roorkee MTech program is not given on the basis of GATE rank. The final shortlisting is done on the basis of Normalized GATE marks were used which is calculated by IIT Roorkee as follows: Normalized GATE marks = Normalized marks out of 100 or Marks*100\Maximum marks awarded in the paper that year For example if a candidate has scored 64 marks and the maximum marks given that year are 92, the Normalized GATE marks are 64*100/92=69.57. The table below comprises the expected GATE 2023 cut-off for IIT Roorkee based on the previous year's cut-off trends. MTech Course Cutoff Alternate Hydro Energy Centre 760-839 Architecture & Planning 650-844 Biotechnology 570-577 Civil Engineering 656-780 Chemical Engineering 650-657 Computer Science & Engineering 840-844 Disaster Mitigation & Management 700-710 Electronics and Communication Engineering 736-750 Electrical Engineering 760-779 Mechanical and Industrial Engineering 748-785 Read more
