I've participated in LIT for the last two years, and I highly encourage others to try it out! LIT CTF in particular was a really fun introduction to CTF contests (with the added entertainment of rickrolls, among us references, and obligatory codetiger orzes). I also really enjoyed the standard round from previous years, as the problemsetters worked hard to make high quality problems.

I look forward to participating again this year!

Just registered. Can't wait :) One question, when I registered it never asked my grade, so how do they know if my team is an only middle school team?

    Hello :D So normally we look at your schools and see if they match the criterion. Thus, after you fill out your school and eligibility information, you should be all set! Excited to have you at LIT~

      Oh, ok. But, my school has my middle school and high school together. So can I write School name(middle school) as part of my school?

        Yep! Great idea to help us differentiate. We're also planning to add "Middle School" as an option to our eligibility section, so check that out once we're done <3

          Is it okay if we put our school names in Arabic? We don't know the official names in English (not even sure if there are English names)

    Yes, you do not have to compete in both, and leaderboards/prizes are separate for both rounds.

I couldn't find it anywhere, how many computers can we use at the same time in the standard round? This is probably discussed in discord, but I don't want to join

    Everyone on a team can use their own computer if desired.

    We don't track any computers, so theoretically, you can have as many computers as you want taking at the same time! :D

Hi, for the eligible (6 — 12) and non-eligible, does it mean that we have to fill eligible if we are in grades 6 — 12 in school and fill non-eligible if we are college students?
