SSC JE Mechanical Syllabus | Detailed Syllabus For Paper I & II

SSC JE is an exam conducted for the post of ‘Junior Engineer’ in various ministries, departments, and organizations that come under the Government of India. In order to take the examination, a person needs to fulfill certain eligibility criteria in terms of age, educational qualification, etc. To get now about this in detail, please follow this linkWhen we talk about educational qualification, it requires one to have a degree or diploma in one of the following streams: Mechanical Engineering, Civil Engineering, and Electrical Engineering. The SSC JE Exam is conducted in 2 stages – Paper-I and Paper-II. Paper-I is an objective type paper, while Paper II is descriptive. For a detailed scheme, please visit here. A lot of times we struggle to understand the paper pattern and the syllabus of the exam. This article aims to help you with this. Here we will get an insight into the SSC JE Mechanical Syllabus.

The Pattern for Paper I & Paper II – SSC JE Mechanical Syllabus

The examination consists of two papers. Paper-I is a computer-based examination and Paper-II is the descriptive type. Detail of these papers are mentioned below:

Papers/ Mode of Examination Subject No of Questions/ Maximum marks Duration
Paper-I (Objective Type) Computer Based Examination (i) General   Intelligence and Reasoning

(ii) General   Awareness

(iii) Part-A
General Engineering
(Civil & Structural)
General Engineering (Electrical)
General Engineering (Mechanical)











2 Hours (40 mins extra for people using scribe)
Paper-II (Descriptive Type) Written  Examination Part-A
General Engineering
(Civil & Structural)
General Engineering (Electrical)
General Engineering (Mechanical)
300 2 Hours (40 mins extra for people using scribe)

The Paper-I consists of d multiple-choice questions only. The question paper will be set in both the languages i.e. English & Hindi. There is a negative marking in Paper-I which is of 0.25 marks per each wrong answer. For Paper-II, we find no mention of negative marking in the official notification.
