THE PAPER IS EXPLAINING TO VERY MUCH EXTENT BUT DOESN'T SAY ANYTHING ABOUT VARIOUS STREAMS SUCH AS I.T. & C.E.
HAVE EVERY ONE GOT THE SAME PAPER REGARDLESS OF THE BASIS OF THEIR STUDY , IF SO, THEN I THINK QUESTIONS ON IMPEDENCE & FLIP-FLOPS CAN BE COVERED ONLY BY ELECTRONICS STUDENTS

yes indeed but i try to keep a balance between all papers so they cater to all anyways gud to see u gained from it
