SSC JE Mechanical Engineering

shape Introduction

SSC JE 2018-19 – First Stage CBT, conducted in online Mode, has: a duration of 2 hour [2 hour 40 Minutes for eligible PwBD candidates accompanied with Scribe], a maximum score of 200 marks and consists of 3 sections, namely – General Intelligence and Reasoning, General Awareness and Technical Ability. The 3 sections are not separately timed. There is a Negative marking in SSC JE First Stage CBT and 0.25 marks are deducted for each wrong answer. The below sections gives the detailed information about SSC JE Mechanical Engineering.
SSC JE Selection Process shall involve three stages: Paper-I - Computer Based Examination, Paper-II - Descriptive Test and Document Verification (DV). Selection is made strictly as per merit, on the basis of all recruitment stages.

shape Pattern

  • The Computer Based Examination is Objective Type in nature consist of Multiple choice questions.

  • The dates of examinations indicated below are tentative. Any change in the schedule of examinations will be informed to the candidates through the website of the Commission.

    • 1. The Examination will consist of two Papers i.e. Paper-I (Computer Based Examination) and Paper-II (Descriptive Type). Details of these Papers are as follows:
    Papers Mode of Examination Subject Number of Questions/ Maximum Marks Time Duration (For all three Parts)
    Paper-I Objective Type (Date of Examination : 23rd Sep to 27th Sep 2019.)

    Computer Base Examination    		 General Intelligence and Reasoning 50/ 50 2 Hours
    General Awareness 50/ 50
    Part-A General Engineering (Civil & Structural) or Part-B General Engineering (Electrical) or Part-C General Engineering (Mechanical) 100/ 100

    2. In Paper-I and Paper-II for General Engineering, the candidate will be required to attempt only the part as per option given in the application form filled by the candidate. In other words, the candidates appearing for the post of Junior Engineer (Civil), Junior Engineer (Quantity Surveying & Contracts) are required to attempt Part-A (Civil & Structural) of Paper-I and Paper II and the candidates appearing for the post of Junior Engineer (Electrical) are required to attempt Part-B (Electrical) and the candidates appearing for the post of Junior Engineer (Mechanical) are required to attempt Part-C (Mechanical) of Paper-I and Paper-II failing which their candidature will be rejected.
    3. The Paper-I will consist of Objective Type, Multiple choice questions only. The questions will be set both in English & Hindi.
    4. There will be negative marking of 0.25 marks for each wrong answer in Paper-I. Candidates are, therefore, advised to keep this in mind while answering the questions.
