Is it because am dragged down to my actual level or is it related to some test handling strategies .?

that's 6 in a row. while that may seem like a lot, it isn't.
in fact -- if you randomly select "right" or "wrong" for each of 41 answers in a row, then it is about 40-50% probable that you'll see at least one run of 5 in a row.
therefore, you are probably seeing nothing except the effect of pure randomness.

if you want to simulate this phenomenon without taking a whole test, take out 41 of the 52 cards in a standard deck, shuffle them, and note strings of red-red-red-... or black-black-black-...
there will be more strings than you probably expect.
