Maharashtra SSC Mechanical Technology Pre-Voc/NSQF case studies
Maharashtra SSC Mechanical Technology Pre-Voc/NSQF · Put your knowledge to work in context.
Mechanical Technology is an NSQF-aligned vocational subject offered at the SSC (Class 10) level under the Maharashtra State Board of Secondary and Higher Secondary Education. It is a pre-vocational subject: instead of a purely academic elective, students study trade-related theory and do workshop-based practical work, so that a Class 10 pass-out already has a recognised, entry-level grounding in mechanical trade skills. The Maharashtra SSC Mechanical Technology Pre-Voc/NSQF case studies are 5 cases and about 3,801 words.
