This blog post follows my previous article titled: BSNL Haryana TTA Recruitment 2013 Notification, Form & Eligibility and is aimed towards providing you the prep materials for BSNL Haryana TTA exam - the Syllabus & Exam Pattern.
First: BSNL TTA exam pattern:
BSNL TTA selection process consists of a written exam, followed by a medical test. What is the pattern of the written exam of BSNL TTA exam? Following tells you about it, along with the mark distribution of papers of BSNL TTA exam.
BSNL TTA written exam for Haryana Telecom Circle (as given in the notification) has three papers, in each of which you need to score minimum qualifying marks: Paper I : General ability test 20 Marks Paper II : Basic Engineering 90 Marks Paper III : Specialization 90 Marks.
This 200 marks question paper has to be answered in 3 hours. Each question weighs 1 mark. There is negative marking in BSNL TTA exam - 0.25 marks for each wrong answer. So be wary of making guess answers!
BSNL Haryana TTA exam Cut-Off:
Minimum cut-off for each paper of BSNL TTA Haryana Exam:
30% (i.e. 6, 27 & 27 marks) for General (OC) category & 20% (i.e. 4, 18 & 18 marks) for reserved category (OBC/SC/ST).
Minimum cut-off for all paper combined of BSNL TTA Haryana Exam:
40% (i.e. 80 marks) for General (OC) category & 33% (i.e. 66 marks) for reserved category (OBC/SC/ST).
BSNL TTA exam pattern of other Telecom circles:
There are some BSNL Telecom Circles, in which the weightage of paper is as below: Paper I : General ability test 100 Marks (2 hours duration) Paper II : Basic Engineering 500 Marks (3 hours duration) Paper III : Specialization 500 Marks (3 hours duration)
This is because, BSNL TTA exams are not held centrally by BSNL. The exam is decentralized individually and is held by twenty-four BSNL telecom circles.
But regardless of above two BSNL TTA exam pattern, you would find that the papers are same (i.e. Paper I is General ability test and so on for other two papers) and the mark distribution among these three BSNL TTA exam papers are almost same: 1:5:5 and 1:4.5:4.5. So if you prepare for BSNL Haryana TTA exam, you can as well appear for TTA exam of other BSNL Telecom Circles without further preparation.
And irrespective of this minor difference in BSNL TTA exam patterns, I found that syllabus of BSNL TTA exams are almost universal and hence is reproduced below (which is available from page: 7 to 9 of the notification).
Syllabus of BSNL TTA exams:
BSNL TTA exam syllabus is as follows:
Paper I: General ability test.
