SSC JE Mechanical Engineering 2023- Exam Pattern

The Examination will consist of two Papers; i.e. Paper-I (Computer Based Examination) and Paper-II (Descriptive). Details of these Papers are as follows:

Note: 

• The candidates will be required to attempt the General Engineering part (i.e. Part-A, Part-B or Part-C) in Paper-I and Paper-II, which has been selected by them, on the basis of their Educational Qualification, in the online application form. 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.
• The Paper-I will consist of Objective Type, Multiple choice questions only. The questions will be set both in English & Hindi.
• 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.
• Candidates are allowed to bring their own Slide–Rule, Calculator, Logarithm Table and Steam Table for Paper-II only. They are not allowed to use such aids for Paper-I.
• Tentative Answer Keys of Paper-I will be placed on the website of the Commission after the Examination. Candidates may go through the Answer Keys and submit online representations, if any, within the time limit given by the Commission, on payment of Rs. 100/-  per  question which is non refundable. Any representation regarding the Answer Keys received through the online modality within the time limit fixed by the Commission at the time of uploading of the Answer Keys will be scrutinized before finalizing the Answer Keys and the decision of the Commission in this regard will be final. Representations on the matter received through any other modalities; i.e., letter, application, email, etc. will not be entertained.
• Marks scored by candidates in Paper-I will be normalized by using the formula published by the Commission through Notice No: 1-1/2018-P&P-I dated 07-02-2019 and such normalized scores will be used to determine final merit and cut-off marks.
• The Paper-II will have to be written either in Hindi or in English. Part paper written in Hindi and part in English will be awarded zero marks.
• In Paper-II, candidates must write their correct Roll Number and Subject at the prescribed places on the cover page of the Answer Book. Candidates must also affix signature and Left-hand Thumb Impression in the relevant columns in the Answer Book. Answer Books not bearing Roll Number, Subject, Signature and Left-hand Thumb Impression will not be evaluated and such candidates shall be awarded zero marks.
• The dates of examinations indicated in the Notice are tentative. Any change in the schedule of examinations will be informed to candidates  only through the website of the Commission.
• There shall be no provision for re-evaluation/ re-checking of scores in the Examination. No correspondence in this regard shall be entertained.
• Candidates are strictly advised not to write any personal identity  e.g. name, roll number, mobile number, address, etc. inside the Answer Book (Paper-II) which will be considered as use of unfair means (UFM). The candidates who fail to adhere to these instructions will be awarded zero marks even if marks are awarded during the evaluation process.

SSC JE Mechanical Engineering 2023- Syllabus

The standard of  the  questions  in  Engineering  subjects  will  be approximately of the level of Diploma in Engineering (Civil/ Electrical/ Mechanical). The details of the syllabus are given below:

Paper-I:
