Exams Prep Master
One of the most soughtafter exams for a career in the engineering field in India is GATE which is scheduled to be conducted from Feb 57 & 1214, 2021. The online registration process will start from September 14, 2020. Every year thousands of students appear for this exam to try their luck for admissions into the best engineering colleges across India.

GATE 2021 Virtual calculator will be provided to all candidates appearing for the entrance examination for their calculations.

The exam pattern of GATE includes numerical questions that require lengthy calculations hence GATE Virtual has been introduced. Check GATE 2021 Exam Pattern

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.

Importance of Virtual Calculator
What makes GATE 2021 Virtual Calculator important?
The fact that physical calculators can’t be used during the exams makes it evident that you need to learn to use an online virtual calculator. While there is not much difference between the online virtual calculator and the physical calculator, getting familiar with the online virtual calculator can make things easier during the exams. Being used during the exam really makes it important for the candidates to get used to online virtual calculators.

The online scientific calculator would be helpful for the candidates for solving problems quickly.

They don’t need to write down the numerical values on the paper every time and calculate, just have to solve on the screen.

This Online scientific calculator will be available for all the candidates who will attend GATE 2021 i.e. same calculator for all.

While in the case of physical calculators, some candidates have more functioning calculators than others. Such candidates always have an advantage over the other candidates.
This method will also help the candidates during exam time whose calculator stops working and will also help those who forgot to carry their scientific calculator with them to the exam center.
Features of Virtual Calculator
Features of GATE 2021 Virtual Calculator

The right side of the virtual calculator contains all the keys for simple operations while scientific calculation keys are on the left hand side.

There is no need for a shift key and inverse key as inverse functions have separate keys.

All function keys are grouped together.

Candidates need not to press SHIFT or INV keys since the inverse functions have separate keys.

Trigonometric functions and Hyperbolic functions will be grouped together.

The inverse functions will be placed below the respective functions.

At the top of the virtual calculator, two display boxes will be provided. The top box will indicate the sequence of the keys pressed during calculation for reference.

The second box indicates the actual values entered or obtained after calculations.

The exam pattern for all 25 papers that consist of both multiplechoice questions and numerical type questions.

Multiple Choice Questions (MCQ): These questions are objective in nature, and each will have four answers, out of which the candidate has to mark the correct one.

Numerical Answer Questions (NAQ): For these questions, the answer is a real number, to be entered by the candidate using the virtual keypad. No choices will be shown for these questions.

Multiple Select Questions (MSQ): These questions are objective in nature. Each question will have a choice of four answers. Out of which, one or more than one choice(s) are correct. However, there are no partial marks awarded for choosing partially correct combinations of choices or any single wrong choice.

There will be no negative marking in NAT and MSQ questions.

Questions carrying 1 mark each, 1/3 marks will be deducted as a penalty of marking the wrong answer.

For questions carrying 2 marks, 2/3 marks will be deducted for marking an incorrect answer.
