Ques. What is the GATE cut off for MS by research program at IIT Madras mechanical branch?

● Top Answer By Kunal Patil on 23 Jul 21

Ans. There is no cut-off score of GATE which is needed for MS by research at IIT Madras mechanical branch. IIT Madras follows a three-step process for admitting students. GATE Initial Screening - You will need at least 65% in your undergraduate and a decent GATE score of around 600+ to get a call for the written exam. This GATE score changes each year based on the number of applicants, the difficulty level of the exam, and various other factors. Written Examination - A written offline or online test will be conducted by the institute next. The syllabus is the same as that of GATE. Interview - If you qualify the cut-off score set internally for the written exam, you will sit for an interview with a panel of professors. Now finally after the whole process is completed, they will release results and offer admissions. The weightage followed by the institute for the final merit list is as follows. Undergraduate percentage - 20% GATE Score - 40% Interview - 40% So, there is no fixed cut-off GATE score for MS at IITM. Read more

Ques. How did you prepare for signal and systems for the GATE?

● Top Answer By Aniket Ranjan on 08 Jan 21

Ans. While there is no set rule for preparing for the signal and systems module of GATE, there are usually two routes or a combination of both that is advised to students. You can either focus on theoretical books and samples like Julius O Smith to study or you can follow online learning tutorials like Edx open software to get clear concepts. Preparation Tips: To begin with, students must always have an in-depth understanding of the foundation subjects. This means starting your study module from between will only cause you to have unclear concepts. It is an exceptionally important topic, and hence students must focus on understanding the concept of Impulse Response and Convolution. Learn the impact of shifting and scaling operations on the waveform to understand continuous and discrete-time signals. For problem-solving questions, it is important to focus on Properties of transforms, analysis and synthesis equations, and common transform pairs. If you have the time, try to learn about all the properties since it can be asked as a direct question. The Fourier transform and Laplace transform are two very important concepts that can contribute to higher marks because of its direct approach. Students must also study the final value and initial value theorem with stability verification. The idea of stability and causality in Z Transform and Laplace can be very scoring if system properties need to be identified from the pole-zero plot. Students can also practice drawing two separate types of waveforms keeping sampling frequency and Nyquist frequency in mind. The concepts of Nyquist Rate, Nyquist Frequency, and Band-Pass sampling theorem are all incredibly important. Study Material: For practicing and learning materials students can find the following. Main Text Book by Schaum series Signal Systems by Prof SC Dutta Roy or Oppenheim Kreatryx Practice Question booklets GATE questions from previous years Signals & Systems has the highest weightage of marks and so it can easily become a high-scoring subject if prepared well. Practicing a large number of problems while understanding core concepts is mandatory to get a score in the subject. Keeping these points in mind will surely help students in getting a good score in signals and systems for GATE.Read more

Ques. What German Universities give admissions through GATE?

● Top Answer By Indrita Ganguly on 08 Jan 21

Ans. German Universities are a great option for Indian students that are looking for well-designed academic courses in Engineering and Technology on a master’s level. While the main exams that are required for admissions in German Universities are mandatory TOEFL scores and GRE in some institutions, there are some universities that also accept GATE scores. Universities across Germany focus more on students’ academic performance as opposed to entrance test scores. Students are required to submit a subject-wise score sheet where they are then assessed based on the average credit score for each subject. Additionally, GATE scores only help add to your academic transcripts and increase your credibility for admissions. Students are selected based on their overall profile, including SOP, Resume, credit work, academic transcripts, work experience, entrance test scores, and more. There are two major Universities in Germany where GATE scores are valid and can be submitted to enhance your profile. Technical University of Munich (TUM): Known to be one of the leading universities in Germany, TUM accepts GATE scores and require Indian students to additionally provide relevant IELTS or TOEFL scores along with it. Students can apply for master’s programs in the faculty of Civil Engineering and Survey, Mechanical Engineering, Information Technology, and Electrical Engineering with a valid GATE score. Apart from having good scores in GATE and TOEFL, students are also required to have relevant scores in a BTech degree in order to be considered for admissions at TUM. The application process at the institute for the September semester begins in January. RWTH Aachen University: The university offers degrees in collaboration with the Imperial School of London and offers admissions for Master’s programs based on relevant IELTS/TOEFL and GATE scores. The main faculties that accept GATE scores are Biomedical Engineering, Electrical Engineering, Information Technology, Geophysics, Computer Engineering, and Automotive Engineering. Students are required to have a bachelor’s degree in a relevant field of study in engineering. Students must have a minimum score of 90 percentile in GATE. Applications for the summer semester begin in September and the winter semester begins in March. The given information should be helpful for students looking to apply to Universities in Germany with GATE scores.Read more

Ques. Can I get admissions to IIT’s without GATE?

● Top Answer By Bhavya Rawal on 08 Jan 21

Ans. GATE is an online competitive exam conducted for qualification to ME, MTech, or P.hD. programs for admissions in top institutions like IIT, NIT, IIIT, and other institutes in India. It is conducted on the behalf of NCB and the Ministry of Human Resource and Development, Government of India. For admissions in any of the IIT branches, students have a few other alternatives to get qualified than just appearing for GATE. Admissions can be given under the given circumstances: Eligibility: Students who have graduated in Engineering with a degree from IIT are exempted from appearing for GATE examinations and can directly apply and appear for a written test. Students who have completed their BTech degree from another university but have a minimum CGPA of 8.0 and above consistently in the last two years, need not appear for GATE. These students can directly appear for the written test and personal interview round. Institute: Students who have an Engineering degree from a Centrally Funded Technical Institute (CFTI) and have a high CGPA of above 8.0 can be exempted from appearing for GATE. The criteria are only accessible within certain campuses of IIT depending upon the branch of study chosen. Sponsored category: Some IIT campuses also offer direct admissions under the sponsored category for top industry personnel or for individuals in academia. For high-level academicians, admissions to Master’s or Ph.D. programs can be done under the Quality Improvement Program (QIP). Integrated Course: For students who do not want to appear for GATE but are still looking at a master’s degree from IIT, you can opt for the 5-year integrated program (MTech+PhD). In order to be eligible for admissions to this program, students must mandatorily have a CGPA of 7.5 and above in a relevant field of Engineering. Furthermore, students who have more than 2 years of work experience and are working for companies that have any links with IIT and sponsor students for master’s courses can be exempted from providing GATE scores for admissions.Read more
