Non-Technical SectionIt will have 60 questions which include questions from General Knowledge, Reasoning, Numerical ability/Quantitative problems and English. The standard of questions is same as of SSC CGLE . English covers almost one third of this section i.e. 20 questions. 15 questions from Numerical ability and Reasoning each and 10 questions from GK.English will cover antonym/synonym, direct/indirect speech, idioms, conjunction, active and passive voices, one word substitution, one passage, error correction, prepositions.Some important points to be considered for the written test: Keep this in mind that unlike most of the PSU exams, there will be no negative marking, so my personal advice will be to attempt all the questions. Non-Technical section has quite easy questions so first attempt this section (if online test settings allow it), it will ensure that you dont miss easy question due to paucity of time or last minute hurry. Technical section has Physics and Math questions so preparation can be started with NCERT books of 11th and 12th Syllabus of Physics and Maths can be covered by referring IIT-JEE prelims questions. Go through the notes from reputed institutes for this.This will cover almost 80% of technical section. In Physics, focus more on Mechanics and Thermodynamics in particular. Similarly in Math. focus on Matrix, Coordinate Geometry and Differential Equations. Some of the questions in technical section will be of graduation level so please refer 1st year Physics and Math. of B.Tech./B.Sc. but my advice will be to focus more on IIT-JEE notes of 12th standard as it will cover major portion of the section. As reasoning covers almost 33% marks of the non-technical portion so practicing this will be a good choice instead of memorizing GK factsforms a small part of the exam. Practice SSC CGLE test papers for Numerical Ability and Reasoning preparation. Also overall practice can be done from NDAs previous years papers as it will cover Physics, Math, English and GK. For English preparation, NDA and SSC CGLE test papers will achieve the goal.
