As you all know that there will be a Quiz in the electronics section next monday
the quiz will be till zener diode .
revise all notes for the three sections that you have taken
you will find all these notes here in the forum (so your task now is to download these notes and begin to revise them accurately)
the quiz may contain drawings ,i think this will not disturb you any more
don't hesitate to ask me any question ,either here or in the institute.
best of luck for all of you
