I want to point out to you that the results from which the methods and results I write about came from REAL experiments with REAL Scantrons and the scanton machines. I spent along time working these out. I have tried nearly everything to beat the scantron machine, and I can happily say that it can be done. I would like to thank someone that was essential to making this possible, but I doubt that he would want to be identified. He was one of my teachers. That’s as far as I’ll go with that.Now, let’s get it on with the GOOD stuff!

1. Marking the black lines (Black on Black method)-On the left side of most scan trons 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% ofthe 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 (Erasure 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. -OR- 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 noticeable 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 diagonal 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 gray that is not too dark or too light. I believe this will work because of the same reason as #5.
8. According to Anthony Iannone …This person states that he has worked on maintenance of those wonderful machines that CORRECT those beloved scantrons. Anyway, he states that almost ALL scantron readers work differently. Makes enough sense… anyway, I would think the methods are generally workable for any machine…. only trial and error will tell. “The only way to fool many of the kinds to to fold the edge over or cut it off. But the the machine will pass it trough unmarked, and the teach will probably notice” He also states that it will only work on the 50 question ones as the others are too small…. my own experiments have shown that it all scantron forms can be manipulated. Another suggestion of his make alot of answer keys and stick them into the batch. That is done by filling in “key,” of course. Some machines only accept one answer key at a time, some will change the key each time it runs across one…. this doesn’t exactly help your grade, but it does wreak some havoc. One can also try copy toner, but I’m not going to risk messing up a scantron machine just to see what will happen.
9. 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… 90% of the time it makes the scantron machine malfunction, and not mark it incorrect. The scantron machine grades your test in the following manner (at least the one I have had access to): It takes the maximum number correct from the answer key, say 20. Then for each incorrect answer, it subtracts one from that total. And it only subtracts if there’s a mistake recorded. That is why malfunctions lead to either no markings, or perfect scores.

And as a final note, CHAPSTICK DOES NOT WORK! I don’t know who started it, but I have tried all flavors of chapstick thinking it might be that. But it hasn’t worked. I have tried all different brands of lip balm as well. It still has not worked. Perhaps it worked back in the day, but it doesn’t now.

    Well this might work but they keep getting new scantron papers so I feel it might never work

    well dude the teacher has to look at the sheet before you put it in the scanner and he’ll see ur cheating and u’ll get in trouble!! lol fail

    Should’ve explained more in detail what exactly to do…
    Just saying “erasing the same black lines” doesn’t help me at ALL.
