(Despite first impressions, this post is not about computers.)
EDIT: I made a THA1 Solver where you can try out THA1 hashing. Although, there’s no point to it because you cant visit RogerHub during a test…
Today, I will be authoring a new cryptography algorithm called THA1 (Test Hashing Algorithm Version 1)
THA1 is a very simple method of verifying your (school) test answers so that you can compare with other people afterward :)
Instead of memorizing 1 is A, 2 is C, 3 is E, 4 is B… You can just memorize one big number (ex. 56)
The downside to this is that, you only know get two possible outcomes:

Answers all match

Answers don’t all match
But that’s the point of hashing right?
Requirements:
– Ability to Add
– Ability to Multiply (They’re small numbers, don’t worry)
– Understanding of Modular Arithmatic
– Ability to memorize a 2 or 3 digit number.
Here are the rules for THA1:
1. THA1 will accept only multiplechoice, matching, and truefalse test questions. So, short answer, fillintheblank(s), and free response will not work for this!
2. To start out, each answer is assigned a value.
A is 1, B is 2, C is 3…. Z is 26
True is 1 False is 2
Double letters will have their numbers added up.
For example: AC will turn into 1+3 = 4
3. Multiply each answer by it’s question number MOD 10. Meaning: for #14, if you get B, do 2(b) x 4(#14), not 2×14 because 2×14 is too hard :).. (not really)
Example:
1. A (1×1=1)
2. C (3×2=6)
3. D (3×4=12)
4. D (4×4=16)
5. B (2×5=10)
6. C (3×6=18)
If any of these products are more than 20, take the modular remainder by 20.
Ex:
23 => 3
57 => 17
4. Add up all the sums! Don’t forget to take the remainder of any of the sums are more than 20.
Example:
1. A (1×1=1)
2. C (3×2=6)
3. D (3×4=12)
4. D (4×4=16)
5. B (2×5=10)
6. C (3×6=18)
1+6+12+16+10+18 = 63
(Seriously, if that took you more than 15 seconds, this method will not work for you…)
That’s it! You’re done. After the veryshort 6 question test, tell people "69" (it was a coincidence, i swear). If other people get answers that are different from yours, then one of you missed at least one question. (Either that or one of you did your math wrong.)
Yeahh… there might be some resonance (lol) or even a better way to hash test problems. That’s why this is only Version 1. If you have any classes with me, we should try this out sometime :)
Another example:
1. True (1×1=1)
2. False (2×2=4)
3. True (1×3=3)
4. True (1×4=4)
5. A (1×5=5)
6. B (2×6=12)
7. D (4×7=28 = 8 Mod 20) <<So, use 8 instead of 28 on this one.
8. C (3×8=24 => 4) << same thing here
9. E (5×9=45 => 5)
10. AB ((1+2)x0=0 => 0) <<Remember, AB turns into 1+2, which equals 3. Also, because 10%10=0, you use 0 instead of 10.
11. AD ((1+4)x1=5)
12. AC ((1+3)x2=8)
13. AE ((1+5)x3=18)
14. BC ((2+3)x4=20 => 0) << 20 remainder 20 equals 0, not 20.
So, 1+4+3+4+5+12+8+4+5+0+5+8+18+0 = 77
Your THA1 Hash is 77!
Yay!
Yeahh. Extra math.. Not fun. But, if you’re really anxious about your test score, this is a foolproof way to remember your test answers. Granted that you didn’t do the math wrong.
If you’re a straitB student, don’t even bother using this. This is meant for Asians that get 100%’s frequently.
Wait, so did you get 77? If not you got one of the problems wrong :)
And Happy Thanksgiving again…

In other news… I broke the shelf thing that was in my locker today. I was trying to get it out and the hinge came off. SO, i just threw it away..
Now that i think of it, I should have recycled.

=_= i don’t need an incentive.
DONT FEEEL DESERTED!
WAVERLY IS HERE!
okay, so i meant to sound like idk, superman or something, but..yeah…
Well, you should aim for 100% right?
So, this will be your incentive to get 100%. Because if you do, you can use THA1 :]
I just made it up on the spot.
I think THA1 is too much work for practical use. ):
Maybe it’s better to just remember the questions..
“That’s it! You’re done. After the veryshort 6 question test, tell people “69” (it was a coincidence, i swear)”
lol :]
“This is meant for Asians that get 100%’s frequently.”
are you referring to yourself in every subject but Spanish? O:
haha (:
this is so cool O:
did you think of this yourself?
or is it like, some universal..nvm. =__=’
but it’s quite a lot to think through after taking the test, and if i were to attempt this, i’d probably get the numbers all wrong >_>’
especially on tests with 100 multiple choice.
SHUT UP IAMNOTJAMESH
This is a cool method x3
I would try this in Zelaya with you Roger.
But we never (NEVER!) get multiple choices.
Well, we only get like 5 matching _______”
Maybe we’ll have multiple choices for the final…..
:3 Anyways, thanks for sharing ~
This isn’t for memorizing answers.
That would be cheating.
I didn’t want to say that it’s for “hashing answers”, because people wouldn’t understand what I meant.
THA1 is for making sure that one person’s answers match up completely with another’s.
This would be more like “verifying answers”, and is meant to be done during the test. Not before.
WOW. like im really gonna go through all this trouble to memorize answers.
