Staff Selection Commission-Junior Engineer has always been preferred by

Engineers due to job stability. SSC-Junior Engineer examination is conducted

every year. MADE EASY team has deeply analyzed the previous exam papers and

observed that a good percentage of questions are repetitive in nature, therefore

it is advisable to solve previous years papers before a candidate takes the exam.

The SSC JE exam is conducted in two stages as shown in table given below.

Papers Subject Maximum Marks Duration

Stage 1:

Paper-I : Objective type

(i) General Intelligence & Reasoning

(ii) General Awareness

(iii) General Engineering : Civil & Structural

50 Marks

50 Marks

100 Marks

2 hours

Stage 2:

Paper-II : Conventional Type

General Engineering : Civil & Structural 300 Marks 2 hours

Note: In Paper-I, every question carry one mark and there is negative marking of ¼ mark for every wrong answer.

Candidates short-listed in Stage 1 are called for Stage 2. On the basis of combined score in Stage 1 and Stage 2, final

merit list gets prepared.

MADE EASY has taken due care to provide complete solution with accuracy. Apart from Staff Selection Commission-Junior

Engineer, this book is also useful for Public Sector Examinations and other competitive examinations for engineering graduates.

I have true desire to serve student community by providing good source of study and quality guidance. Any suggestion

from the readers for improvement of this book is most welcome.

With Best Wishes
