  • As the candidates will not be allowed to use a physical calculator, they will have to use the virtual calculator during the exam.

  • The Question Paper will be set within the consideration of the requirement of a virtual calculator by the authorities, which will not be an issue for the candidates if practiced well beforehand. 

The idea of using a virtual calculator in GATE exam was adopted in the year 2015 but it was not implemented in the 2015 examination. But in 2016 the exam conducting body that is IISc, Bangalore implemented the use of GATE Virtual Calculator instead of any kind of physical calculator. So it has become very important for candidates to have a good command over virtual calculator so they can do calculations easily.

Ques. Can I get a seat in PEC Chandigarh (MTech CSE) with a GATE score of 400 Gen in the CAT?

● Top Answer By Arunima Sethi on 05 May 21

Ans. No, it is not possible to get a seat in PEC Chandigarh for M.Tech CSE at the GATE score of 400, being in General Category.  For Round 1, GATE 2020 opening score for CSE was 402 and the closing score was 523.  While, during Round 2, the score was between 379-395 for the General category.  The total seats for CSE at PEC Chandigarh is also limited. There are only 30 seats available for the program, out of which only 19 are for General candidates. Seeing my friend’s experience there, I would strongly recommend you to re-attempt the exam and score well. Try to get an opportunity in top engineering institutes like IITs/NITs.  It is not that PEC is a worse institute, but if you prepare well and give GATE again, you might land into your dream college. Also, a Master's is usually the last stage of academic learning for all. So, it is better to invest your Master's degree time in an excellent institute.Read more

Ques. Is a stipend available in PEC Chandigarh University through a valid GATE score card?

● Top Answer By Rohini Mishra on 02 May 21

Ans. To put it short, yes, you do get a stipend at the PEC Chandigarh University, but it depends on certain terms and conditions.  Getting an SGPA of at least 6.5 in the semesters is the most important condition. If it is less than required in any semester, your next stipend will not come for the next adjacent half. If you fail to do so in the 1st semester, the stipend for the second semester would be lost.  If you score SGPA more than 6.5 in the second sem, the stipend of third and fourth in the second semester combined will re-continue.  And if you fail to reach 6.5 in the second sem, the stipend of the third and fourth sem will discontinue. As there are no separate examinations for the 3rd and 4th sem to judge the eligibility of stipend.  The stipend for the first semester is received by the students without any conditions, so you need not worry about this, as this depends on your GATE score. Read more

Ques. What do you prefer, the GATE or the IES?

● Top Answer By Keshav Jindal on 25 Feb 21

Ans. I would prefer GATE or IES because in GATE the ratio is 10:1 whereas in IES the ratio is 300:1. This makes IES a very tough competitive exam but in GATE it is easier to get good marks and rank higher as the paper is easy and less competitive compared to IES.  The IES exam is tougher than GATE because here a candidate has to excel both in academics and personality. In GATE the questions are concept based and it is easier to solve if all the concepts are clear. Also in the GATE exam, there are 65 questions and the time limit is 3 hours but in the IES exam there are 120 questions and the time limit is 2 hours. So you get less time to solve all the questions.  After qualifying for your GATE exam with good marks, you can apply to any of the big companies with higher packages and it also opens your gate to apply for PSU.   After qualifying for your IES exam, you will get a job as an assistant executive engineer and after 3-4 years of experience, you will get promoted to executive engineer post. Then after many years of experience of like 20+ years, you will get Chief Engineer posts.Read more

Ques. What are the best coaching centres for GATE and IES in Civil Engineering?

● Top Answer By Sabeer Chalana on 23 Feb 21

Ans. There are many coaching centers throughout the country for IES and GATE coaching. However, these 2 institutes enjoy a huge reputation and recognition at the national level due to their experienced faculty and their study material quality. Made Easy: It is one of the best in the field when it comes to GATE and IES coaching. They have the best faculty teaching the subjects for the students.  Their specialty lies in their high quality and concise presentation. One of my friends enrolled in the Delhi center weekend coaching program, which he claimed to be good. Their online test series is one of the best you can opt for. They are prepared keeping the present pattern in mind. The number of students enrolled is hefty and gives you a clear picture of the competition. Some criticize that their teaching lacks depth compared to other institutes. Their courses and tests require analytical knowledge and are more than enough to crack GATE/IES exams. IES Masters: This institute is one of the best in this field and has earned respect for its excellence and quality coaching within a short span of its inception. All the major subjects for all batches are handled by Mr. Kanchan Thakur who is the director of the institute. He has a brilliant command over all the subjects in Civil engineering. The study material of this institute is best and is even recommended for those who choose civil engineering as an optional subject in UPSC exams. One small setback is that other faculties than the director are not on par when compared with the faculties of Made Easy. For the GATE Online test series, you can opt for Made easy test series, and for the IES test series you can opt for IES Masters. If you plan to join made easy to enroll in Super Talent Batch which has all top faculties teaching in this batch. For Classroom coaching for civil engineering in GATE/IES, Super talent batch can be preferred if not then IES Masters. For Postal study course, one can opt for IES masters.Read more
