- Well, throughout my lifetime, I've learned one thing. Scantron tests
- are a bitch. So this text will hopefully help you out. I'd like to point
- out that the results that the methods and results I write about came from
- ACTUAL experiments with ACTUAL Scantrons and Scanning Machines. I spent a
- long time working these out. I have tried virtually everything there is
- to try to beat the scantron machine, and I can happily say that it can be
- done. Now, I am not endorsing that you use these methods to get the first
- letter of the alphabet on your report card. These are for informational
- and entertainment purposes only. If you do use these methods, I, of
- course, am not at all responsible and blah blah blah.
- I would like to thank someone that was essential to making this file
- 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 on to the good stuff...
-
- 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 (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 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
- #5.
-
- 8. YOU FILL IN THE CORRECT ANSWER!
-
- *******ADDED SINCE LAST POSTING OF THIS DOCUMENT*********
-
- 9. According to Anthony Iannone <aiannone@maple.nis.net>...
- 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 machiene 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.
-
- 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.
-
- Okay, that's enough for methods.. because... I don't know anymore. I
- don't get much access to a scantron machine much anymore... SO, I'll just
- ramble about the scantron machine in general.
-
- 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.
- Let's see what else is there to talk about... I would go in to the anarchy
- way of attack of scantrons, but that is not your goal... besides, if you
- need me to tell you how to fuck things up, you have to be retarded. Also,
- as another note of privacy, I am including my PGP key.... big whoop.

- ********End of updates since the last postin*********
-
- Okay that's about it. All I ask is that if you read this, please send
- me an e-mail. I'd just like to know how many people are getting this.
- I'd prefer that you not use an anon remailer, but if you are so paranoid
- that you believe that the government is taking the time to care
- particularly about you, go ahead.
-
- Now for my plea of help. I'd like this list to grow. I have tried
- many hacks. But I have not tried them all. I seriously doubt that this
- is all of the hacks that you can use. If you find anymore, please send it
- to me, so that I can update this list periodically.
-
- If you go on IRC, I can be found damn near everywhere. I go by the
- name of DSoldier. I tend to frequent the Undernet, though.
-
- 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.
