About the WBBSE Madhyamik Electronics (Vocational) Exam
The WBBSE Madhyamik Vocational Electronics & Hardware (NSQF Level 2) syllabus equips Class 10 students with foundational skills in electronic technology. Key domains include identification and testing of passive components (resistors, capacitors, inductors) and active devices (diodes, BJTs, FETs), soldering standards, PCB assembly and desoldering techniques, operation of test instruments (analog/digital multimeters, cathode-ray oscilloscopes, signal generators), design and maintenance of AC-to-DC regulated power supplies and battery charging circuits, and systematic fault diagnosis of consumer electronic equipment. Note: This practice question bank is an English-language MCQ study adaptation for the WBBSE Madhyamik Vocational Electronics examination.
Assessment
Madhyamik vocational subject - Electronics: 1-hour-45-minute theory paper in the Optional Elective sitting, with practical/skill assessment conducted by the Sector Skill Council or the school concerned.
Time Limit
Theory 1 hour 45 minutes; practical/skill assessment conducted by the Sector Skill Council or the school concerned
Passing Score
WBBSE reports each subject on a seven-point grade scale: AA 90-100, A+ 80-89, A 60-79, B+ 45-59, B 35-44, C 25-34 (marginal pass) and D below 25 (disqualified). Grade C is therefore the minimum subject grade and a D in any compulsory subject makes the overall result unsuccessful. Division bands are separate: 1st division 480+, 2nd 360+, 3rd 272+ out of 800.
Exam Fee
WBBSE does not publish a single per-candidate examination fee with the Madhyamik routine. Enrolment is made by the school online through wbbsedata.com within the Board's registration window, and the amount payable is set by the Board's enrolment circular for that session. Confirm the current figure with your school or the Board's notification rather than relying on a quoted estimate.
