BSNL TTA/JE exam syllabus, cut off marks, merit list 2016




BSNL TTA exam Overview

BSNL has recently issued notification for recruitment of Junior Engineers post and syllabus, cut off marks of the same is provided in this post. This is the first time when it is conducting All India Online exam for TTA the post. Earlier it was conducted at state level. Now onwards it will be a all India examination.

BSNL TTA Job provides best work opportunity for Diploma Engineer students of Electronic, Telecommunication, Electrical, Radio, Computers, Instrumentation and Information Technology. The examination Syllabus is common for all streams and divided in three parts which are General ability Test, Basic Engineering and Specialization. BSNL TTA exams detailed syllabus shown below

Part – I

General Ability Test – 20 Marks

Candidate’s comprehension and understanding of general English is tested through simple exercises such as provision of antonyms and synonyms, this shall also include questions on current events and general knowledge which can be observed by a diploma holder.
