.
ඒ කාලෙමයි අපි හිතුවෙ අපි කරපු IPE lab exercises, CF වල අපි හදපු lab sheet answers,  එතකොට තව past papers වලට අපි ලියපු උත්තර මෙහෙම නෙට් එකට දානවා කියල. හැබැයි මේවා කෙලින්ම copy කරලා විලි ලැජ්ජාවක් නැතුව moodle එකට  upload කරල ෂේප් වෙන්න නම් එපා!! දන්නැති, තේරෙන්නැති දේවල් ගැන පොඩි අදහසක් වත් ගන්න පුලුවන් වෙන්නයි මේවා දාන්නේ....
