[Educated]

The Question Booklets are divided into five sections :

• Aeronautical
• Mechanical and Production
• Metallurgy
• Electrical and Electronics
• Computer Science

General Awareness - 15 Questions - 15 Marks

General Engineering - 25 Questions - 25 Marks

Questions specific to the respective divisions specified above - 120 Questions - 120 Marks

Total - 160 Questions - 160 Marks

Important Note(s) :

• The Question Booklet for Mechanical and Production Disciplines will be the same and candidates will have to answer questions for both Mechanical and Production Branches.
  
• The Question Booklet for Electrical and Electronics Disciplines will be the same and candidates will have to answer questions for both Electrical and Electronics Branches.
  
• There are no negative marks for incorrect answers.
  
• Please use the blank pages provided at the end of the Question Booklet for rough work only.
  
• Candidates will be required to appear for the Written Test at their own expense and will have to make their own arrangements for boarding and lodging at the place of the Examination.

Further consideration of the candidature after the Written Test will be subject to the following points :

• Candidates having passed the final Engineering Examination in the specified Branches of Engg. indicated in the Advertisement, from any recognised Institution/University, with 60% marks in the Aggregate of all Semesters for General/OBC and 50% Marks in the aggregate of all Semesters for SC/ST Candidates.
  
• Verification of Qualifications, Marks scored, Age, Caste (for SC/ST/OBC only) PWD (Person with Disability)/Ex-Servicemen etc.

INSTRUCTIONS TO CANDIDATES REGARDING ANSWER SHEETS :

• Use only HB Pencil to mark the Ovals in the Answer Sheet.
  
• Use Ball Point Pen to fill the Boxes (ie for the Question Booklet No., Roll Number, Date of Birth and Signature.)
  
• Indicate the Question Booklet Series and Question Booklet Serial Number in the space provided on the OMR Answer Sheet without fail.
  
• Please mark the relevant Ovals against the columns like Series, Category, Quota and Main Branch of Engineering as applicable to you.
  
• Mark your answer only in the appropriate space against the Number corresponding to the question you are answering. Darken the response for each question:
  A B C D (If the answer to the Question is option B , then it needs to be darkened )
• Please ensure that the Ovals are completely darkened.
  
• In case of any mistake while marking, please erase the mark completely and fill the correct Oval again. Do not leave stray marks/half filled Ovals on the Answer Sheet.
  
• Rough work must not be done on the Answer Sheet. Use the blank pages given at the end of the Question Booklet for rough work.

[Bandish 555]

Hey!
Thanks a lot..! I was in need of this from a long time..! Well can you provide me with the sample paper or previous papers? I need to prepare for the exam..! Thanks again...! I need the paper for Design Trainee [electrical field]...!

[Recruiter]

Hey!
I don't have a sample paper but just the idea about it...!
Here :

Total no.of questions 160(25+135)
25-general(eng,gk,apt)
135-tech

though there are no sections,i'm giving u the round figures....
ENG-of Normal level(stress on grammer-something like correction of sentences)
GK-of various areas(don't prepare,no problm if u don't know)
APTITUDE-Basics,examples in R.s.agarwal will suffice(work-time,proportion,profit-loss...)

TECHNICAL-
note: calculations are bit clumsy(prepere mentally for that)
Major portion
- Networks( kcl,kvl and other basics)
- Machines(mainly DC)
- Measurements(if u r not familiar,jus remember main points about different instruments preferably from some book meant for psu)
Minor portion
-Power system
-control system(root locus)
-others(less)
