GATE 2022 Physics Exam Syllabus, Pattern, Marking Scheme, Dates, Result

GATE 2022 Physics Exam – Here we will discuss in complete details about GATE 2022 Physics exam. We will discuss about GATE 2022 Physics syllabus and exam pattern.

GATE is conducted jointly by the Indian Institute of Science (IISc), Bangalore and the seven IIT’s (IIT Bombay, Kanpur, Delhi, Guwahati, Madras, Roorkee and Kharagpur).

Qualifying in GATE is a mandatory for admission and/or financial assistance to:

  • Doctoral programs and Master’s programs in Engineering/Technology/Architecture
  • PhD in relevant discipline of science, in institutions that are supported by the MHRD and other Government agencies.
  • Even in some institutions and colleges, which admit students without MHRD scholarship/assistantship, qualifying in GATE is a mandatory.
  • Further, many PSUs (Public Sector Undertakings) use GATE score in their recruitment process.

GATE Physics 2022 Exam Schedule

GATE 2021 Physics Exam Date – 12th February 2022 (Saturday)

GATE 2021 Physics Exam Timing – 09:00 – 12:00 hrs (Forenoon Session – FN)

Eligibility for GATE 2022 Exam

A candidate who is currently studying in the 3rd or higher years of any undergraduate degree program OR has already completed any government approved degree program in Engineering / Technology / Architecture / Science / Commerce / Arts is eligible for appearing in the GATE 2021 exam.

Age Limit: There is no age limit specified for the candidates.

Scheme of GATE 2022 Physics Exam

GATE exam will be in ONLINE Computer Based Test (CBT) mode where the candidates will be shown the questions on a computer screen. GATE exam will be of 3 hours and there will be 65 questions of total 100 marks.

During the examination a Virtual Scientific Calculator will be available on the computer screen.. Wristwatches, Personal, mobile phones, calculators or any other electronic devices are NOT allowed in the exam hall.

For rough work scribble pads will be provided to the candidates.

Pattern of GATE 2022 Physics Exam

There will be two section containing 65 questions carrying a total of 100 marks.

The General Aptitude section there will be 10 questions carrying a total of 15 marks. These questions will be on General Aptitude (GA), which is intended to test the Analytical Skills and Language. This will carry 15% of total marks

85% of the total marks are devoted to the subject paper containing 25 questions carrying 1-mark each (sub-total 25 marks) and 30 questions carrying 2-marks each (sub-total 60 marks) consisting of MCQ, MSQ and NAT Questions.  There will be 55 questions carrying a total of 85 marks from the subject.

GATE 2022 Physics Exam would contain three types of questions

  • Multiple Choice Questions (MCQ) – these questions carry or marks each. These questions will have a choice of four answers, out of which the candidate has to select (mark), the correct answer.
    • Negative Marking for Wrong Answers:
      • For 1-mark MCQ, Negative Marking for Wrong Answers is 1/3 mark.
      • For 2-mark MCQ, Negative Marking for Wrong Answers is 2/3 mark.
  • Multiple Select Questions (MSQ) carrying 1 or 2 marks each in all the papers and sections. These questions are objective in nature, and each will have choice of four answers, out of which ONE or MORE than ONE choice(s) are correct.
    • Negative Marking for Wrong Answers
      • There is NO negative marking for a wrong answer in MSQ questions. However, there is NO partial credit for choosing partially correct combinations of choices or any single wrong choice.
  • Numerical Answer Type (NAT) Questions- these questions carry or marks each. The answer is a signed real number for these questions, which needs to be entered by using the virtual numeric keypad on the monitor (computer’s keyboard will be disabled).The answer can be an integer only such as 10 or -10. The answer may be in decimals as 10.1 or 10.01 or -10.001. There will be instruction in question up to which decimal places; the candidates need to make an answer. Appropriate range will be considered while checking the numerical answer type questions so that the candidate is not penalized due to round-off errors. Wherever required and possible, it is better to give NAT answer up to three decimal places.
    • Negative Marking for Wrong Answers
      • For a wrong answer in NAT questions there is NO negative marking.
