Is a Calculator Allowed in the GATE Exam?

The answer to the query is, is a calculator allowed in the GATE exam? Yes, a Calculator is allowed in the GATE exam. Still, that calculator is not similar to a physical calculator used at the college level or a computing calculator with addition, subtraction, multiplying, or dividing commands.

The GATE will provide aspirants with a virtual scientific calculator, which the candidates can use to respond to the appropriate questions using a mouse. The GATE exam contains complex calculations and lengthy decimals up to three points and numerical values, which becomes a bit problematic for students to calculate on time as there is limited time available for students in the GATE exam.

How to Use the GATE Calculator?

Students encounter a new problem using a virtual calculator on exam day, which can be tricky. Hence they are advised to have a hands-on understanding of the online virtual calculator preparatory for the exam. By solving the query, Is a calculator allowed in the GATE exam? Here are a few components and operations on how to use a virtual calculator:
