An MS from IIT Kanpur is considered to be a highly respected and prestigious degree. The MS program at IIT Kanpur is reputed for its focus on excellent research and its strong focus on practical, hands-on learning. As an MS student, you get to work with some of the most experienced and respected scholars and researchers in their fields, which gives an insight into the latest industry developments and trends.
Additionally, not being located near metropolitan areas, IIT Kanpur gives a peaceful learning environment and students don’t spend much time partying or clubbing. Although it is a 2-year program, with the right determination one can complete it in 18 months also. If you are true to your passion you can also complete a Ph.D. under an experienced thesis advisor and won’t have to go to a foreign university for a Ph.D.
Overall, an MS from IIT Kanpur is a valuable and highly esteemed program that offers many opportunities in terms of career and professional advancement. Although it is challenging, the learning experience is worth the effort.
It depends on your career goals. GATE offers more options for engineering students. It is an all-around examination. You can go for MTech, PSUs, MS, and FRM. If you want more options, GATE will be better for you.
If you want to do an MBA, after graduation, CAT will be the better option. Almost all top B-Schools accept CAT scores for MBA.
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
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 -
Also, note that BITS take admission based on GATE scores as well.
Here are some strategies that can help you prepare for GATE and ESE simultaneously.
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.
