MECHANICAL ENGINEERING QUESTIONS – പ്രതീക്ഷിക്കാവുന്ന മെക്കാനിക്കല്‍ ചോദ്യങ്ങള്‍!

ജൂലൈ 31 ന് നടക്കാനിരിക്കുന്ന ഓവര്‍സീയര്‍ / ട്രേസര്‍ – KWA Gr. III പരീക്ഷയുടെ മെക്കാനിക്കല്‍ പോര്‍ഷനായി അവസാനവട്ട മുന്നൊരുക്കം!

The KWA 3rd GRADE OVERSEER Syllabus covers portions from Civil Engineering and Mechanical Engineering. As these Technical exams are equally meant for Mechanical and Civil Engineering candidates, which hold equal weightage for both subjects. KWA OVERSEER GRADE 2 syllabus is almost same as that of kwa overseer grade 3 syllabus

Normally a 50-50 weightage is expected, but it may vary slightly. However, those candidates who score maximum mark from their own stream and manage to score the crucial marks from other stream will be the winner in KWA exams.

Scoring from the basics will do the job for tracer exams. Anway, happy learning and all the best wishes from Team Civilianz for your exam preparations!
