Ques. Which is the best coaching for GATE or IES in Allahabad?

● Top Answer By Aniket Atul Mahulikar on 15 Jan 21

Ans. GATE and IES both exams have almost the same syllabus. If you are residing in Allahabad and looking for the best coaching institute, then you have limited options. Both the papers are highly competitive and require experienced faculty for mentorship.  A few of the coaching institutes have associated industry experts to help GATE or IES aspirants. The top choices from which you can opt for includes:  Mechasoft AIEFA Mechasoft:  It is a good coaching institute with trusted faculty like Mr. A.K. Tripathi. Tripathi Sir is an expert in Control Systems who also teaches some other electronics subjects.  AIEFA:  AIEFA had a collaboration with Gateforum before. Now it’s a separate coaching center. It has poor management and the class schedule is not fixed. They teach in extremely long hours sometimes.  You can also go for self-studies and take the help of online guides. If you find it essential to opt for a coaching institute, you can opt for Mechasoft because the batches are small, and doubt clearing sessions are effective. For online classes, you can opt for Made easy, Times, or Ace academy.Read more

Ques. Is it good to prepare for the GATE and the IES simultaneously?

● Top Answer By Sandip Pal on 14 Jan 21

Ans. If you are preparing for IES then you can also simultaneously prepare for GATE as well with just a little extra effort. The syllabus of IES is quite vast as compared to the GATE syllabus. If your primary goal is to crack IES, concentrate more on the IES and study for GATE parallelly. If you are more interested in GATE, you need to make some extra effort. However, if you are equally interested in both you can follow the strategy given below for preparation. IES Preparation:  Read class notes and solve the workbook regularly.  Make short notes for each subject containing formulas, facts, and the new concepts you learned while reading. Solve previous year’s questions for IES and GATE. Note down the important questions you come across. During revision, go through the short notes you made and the questions too.  Give online and offline mock tests regularly.  GATE Preparation: If you follow a smart study plan you can complete the GATE preparation in just one and a half months. The syllabus for GATE is just like a subset of the IES syllabus. Both of them have several topics in common. You can follow this strategy to crack the exam: One month before GATE, thoroughly read all the class notes. Solve previous year’s question paper as much as possible. Take as many mock tests as you can. 10-12 days before the exam, revise the short notes daily. You can prepare for IES for the whole year and do the major chunk of preparation for GATE in the last 1-2 months. One of my friends followed this pattern for his preparation and was successful. But you don’t have to follow this plan blindly, you can make up your own strategy too.Read more

Ques. What is the difficulty level of the BITS HD exam compared to the GATE?

● Top Answer By Sahil Sachdeva on 14 Jan 21

Ans. GATE exam focuses on how much the students' concepts are clear and how they can apply them for solving the questions. Most importantly, it contains numerical questions, so it would be better to expect fewer theory questions in the GATE exam. Whereas, BITS HD exam contains the majority of theory questions. You are required to solve more problems in less time. You also have to prepare for aptitude and English. These sections are quite scoring and help to get a better score.  Difficulty Level - Comparison: GATE consists mostly of numerical, while 80 to 90% of the questions in BITS HD are theoretical.  You will hardly find 10 to 15 numerical questions in HD paper out of hundred questions. Numerical questions are not like GATE. These are mostly the formula and solve type. Nevertheless, some numerical may be found very tricky.  You need to have a thorough understanding of your syllabus for BITS HD. Theoretical questions will come from anywhere, and they will test your understanding of the respective topic. BITS HD consists of 15 maths questions that are way more difficult than GATE, 15 general English, and 70 engineering discipline questions. One most important thing to add is that BITS have also started admitting students by accepting their GATE score. If you have a 55+ GATE score, you can get admission to BITS.Read more

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

● Top Answer By Angana Nath on 08 Jan 21

Ans. GATE and ESE (Engineering Service Exam) are almost similar, so preparing for one exam ensures complete preparation of at least one portion of the other. Given below is the strategy of preparing simultaneously for GATE and ESE. ESE: Technical Subjects: Read the theory properly and solve ESE objective questions. Solve all the previous year Gate questions of ECE, EE, IN streams. Solve ESE Test series only, do not start with the GATE test series. Non-Technical Subjects: For these subjects, students must put in the daily effort. Each day 15-20 minutes for this is enough. If you keep up this practice sincerely for 5-6 months, there is a good chance you will be able to score more than 300 in ESE prelims.  GATE: Now that ESE is dealt with, go for the GATE test series. As the theory portion has already been covered, start with solving questions. Give at least 10 full syllabus mock tests for GATE.  How to Attempt GATE questions: Attempt all the 1 mark questions. Go for the aptitude and English section. This will provide a break from all the formula questions which have been solved. For the last 30 questions, attempt which questions are easier so that there is time to get back to questions that could not be solved. After the prelims of GATE, you will have 4-5 months to prepare for Mains. In the meantime attempt the previous years’ question paper of UPSC to get an idea about what is asked in the examination. Read standard books to clear basic concepts. Practice is the key to score well in these exams. So, attempt mack-tests for Main as well.Read more

Ques. What is the minimum score of GATE one should secure to get into PSUs?

● Top Answer By Poorva Chourasia on 08 Jan 21

Ans. The GATE cutoff for PSU recruitment is quite high. Only top rankers in the GATE examination have a chance of getting a call for an Interview. PSUs invite almost 4 times the candidates they actually recruit. As only the top rankers have the privilege of choosing the company they want to work in. PSU Recruitment Details: More than 50 PSUs recruit students based on their scores in GATE. To be recruited, candidates must score above the GATE-cutoff and also the cut-off mentioned by the company of choice. Some companies directly recruit candidates through their GATE scores while some only shortlist. Some PSUs conduct an additional test for recruiting candidates. Some of the companies that accept PSU scores are AAI, BARC, BBNL, BHEL, BPCL, CEL, CIL, DMRC, NBCC, NTPC, HPCL, ONGC, Powergrid, THDC, etc. PSU-Cutoff: Given below are the branch and category-wise cut-offs for some of the major companies, for PSU-GATE. PSU Branch/Post For General Category HPCL Mechanical  68.45 Civil 70.04 Electrical 58.64 Instrumentation 44.33 E&TC 73.05 Chemical 56.67 ONGC(2019) Geologist 557 Chemist 690 AEE Production Petroleum 703 AEE Cementing Mechanical 895 AEE Electronics 868 Surface Geophysicist 621 Programming Officer 840 AEE Production Chemical 689 AEE Cementing Petroleum 873 AEE Electrical 841 Well Geophysicist 697 AEE Mechanical 856 AEE Drilling Mechanical 845 Transport Officer 899 AEE Instrumentation 730 AEE Reservoir 847 AEE Production Mechanical 867 AEE Drilling Petroleum 803 MM Officer 923 AEE Civil 915 The GATE Cutoff for ONGC may vary with each vacancy. Candidates must score a minimum of 65% in their BTech graduation to appear for GATE. The salaries offered are almost the same for PSUs that recruit through GATE, but the salaries offered to people recruited for senior positions may differ.Read more
