I do not and can not endorse the use of ANY of these methods except for #8.
If you decide to try this and get in trouble, it is your fault and not mine.
Again, I take no responsibility for your actions.

The scantron machines grade your test in the following manner. It takes the maximum number correct from
the answer key, say 20. Then for each incorrect answer, it subtracts one
from that total. It only subtracts if there's a mistake recorded.
That is why malfunctions lead to either no markings, or perfect scores. The list below can help you create these malfunctions.
1. Marking the black lines (Black on Black method)-
On the left side of most scantrons that I know of, there are black
lines next to question numbers. My hypothesis is that these black lines
tell the machine where to scan. I don't know how it works, but it does,
but not as often to create a great advantage. It works about 25%-30% of
the time. I suppose coupled with actual guessing, this does add to the
probability of getting a correct answer. This is my recommended hack.
This is the hack that will work more often than any other. Do it only on
the ones you can't answer.
2. Erasing the same black lines (Erase method)-
Now this hack is pretty self-explanatory. You erase those same black
lines, only on the ones you can't answer though. Sometimes the machine
skips the question and doesn't mark it at all. This leaves you with a
correct answer.
The machine will record an error and not mark the paper at all,
including the score. This will then allow the teacher to grade it by
hand, where he or she may notice the tampering.
3. Erasing the big black block (Big block eradication method)-
Along the left side is a big black block. It is on the upper part of
the column before the question lines. Occasionally, the machine will just
skip over the whole damn thing but leave you with a 100%. This is
practically impossible to get to work. I have gotten it to work twice out
of hundreds of trials, but it can be done. My reasoning for this is
because there is another similar block at the bottom of the column. I
believe that the big block tells the machine when to begin scanning for
questions. I think that variations in the printing of scantrons probably
produce a block on the bottom similar enough to the erased block. Thus,
the machine sees the block begins scanning, sees nothing to correct and
gives you a 100%. Like I said this is probably less than 1% success, but
it can work.
4. Cutting out that big block (Hole in your head method)-
I have had more success with this than erasing for some reason. Again
this is an all or nothing proposition. If you like gambling, go ahead.
Remember that you will leave more noticable physical evidence.
5. Cross-hatching fill-ins (Cross method)-
This method works about 20%-25% of the time. I believe it is pretty
self-explanatory. I find that the best patterns are diaganol
cross-hatches, or horizontal lines. I can't explain why this works, I
assume you are simply confusing the machine.
6. In-between shading (Grey areas method)-
By in-between shading, I mean finding a level of grey that is not too
dark or too light. I believe this will work because of the same reason as
8. YOU FILL IN THE CORRECT ANSWER!
9. "The only way to fool many of the kinds to to fold the edge over or
cut it off. But the the machiene will pass it trough unmarked, and the
teach will probably notice"
#5.
10. Putting a piece of tape over the black lines (Tape method) - This just does what chapstick was supposed to do... screw up the
scanning light... and jack up everything... what you need to HOPE it does,
is pray that it makes the scantron machine malfunction, and not mark it
incorrect. Best of luck... I hate this method.
