STEP 1
Candidates were required to make through mortise and tenon joint. Most candidates were able to make the joint. However, some of them failed to make the joint.Each candidate’s workpiece was to have one mortise and one pin at piece.
STEP 2
Candidates were required to make single through dovetail joint. Most candidates were able to make the joint. However, few of them failed to make the joint.Each candidate’s workpiece was to have one socket and one dovetail pin at the top
STEP 3
Candidates were required to make through housing joint at the top and bottom of the part of the table frame. Most candidates were able to make the joint correctly.

Note: Question 2 had dovetail joint to cut at an inclination. The students had tough time in cutting the dovetail at an inclination. However, their performance is encouraging from the skills exhibited on the practical scripts. The rebate cut on the question 1 suggests that the students are not provided with adequate tools for such operation. However, their attempt they made on answering the question showed that they have the potential to learn and do practical works.
