If the first question is simply numerical, I would refer you to 4.b.iii.It seems like you can now get points for a question even if you have more than 2 errors (100 points deducted for each error after). How does this work for the first question with the time bonus? If you answer it with lets say 3 errors would it be counted right with a deduction of 100 points or must it be within 2 errors in order it to be counted correct for the bonus?
This is the first year that Codebusters is a national event, so there is no sure way of knowing how many people wish to participate in both events.why do codebusters and circuit lab conflict. I am pretty sure that may people do both events
According to the rules (3.i.i), the timed question is an Aristocrat (mono--alphabetic with spaces) with or without hint. Last year's National trial and I believe the Indiana State trial as well took the timed question at full value if there were less than three errors (see Wisconsin 2018 trial rules, 3.d). In this case nicholasmaurer would be correct.If the first question is simply numerical, I would refer you to 4.b.iii.It seems like you can now get points for a question even if you have more than 2 errors (100 points deducted for each error after).

However, if the answer is non-numerical I agree there is ambiguity. I would assume they mean to apply the bonus if you have two or fewer errors (as this would result in full credit). However, an FAQ would be beneficial.
Yes, it might be fairly complicated as this is a topic reserved for the state/national tournaments. The way I interpret 3.a. I would not expect basic knowledge questions on any CodeBusters exams - everything should be application questions where you are encrypting or decrypting messages using the methods listed in 3.e and 3.fDoes anyone have an idea what is expected in the RSA cipher (3.f.iv)? It seems to complicated for encryption or decryption (especially with a 4 function) so what would be tested? I think either a mathematical crypt-analysis or a basic knowledge of how it works might be it.
Per (f.vi.) at least one of them has to be in Spanish for State and Nationals. So here's an easy standard one in Spanish. It is the first verse of a ridiculous hyperbolic poem: Try to solve it by hand without computers and post how fast you did.

How are you guys studying for this as a team? I want to know so I can get cracking with my teammates.
Furthering that point, once you guys all have a general idea of each code it's probably best that only two of the three people specialize on a specific cipher, as you want to be specialized to work best at any code. Having two people will definitely work better than one person, since at least one other person can quickly look for errors should they be present while the third one focuses on a different code. You don't all want to focus as a group though, since you still want to keep efficiency. This also means the xenocrypt in Spanish, at least two people should know or try and learn some Spanish grammar/vocabulary.How are you guys studying for this as a team?

first just learn how to encode and decode all the different type of ciphers
once you got that down, start practcing by writing ciphers for each other to solve
Finding repeating chunks in the problem can allow you to see patterns and guess what word it is (probably "the", or another another commonly used word). Letter frequency also helps a lot if you know the order (ETAOIN)Any good advice on solving patristocrats?
