Welcome back to Code Breaking 101
Rookie Recruits, you are here because you didn't quite make the cut first time around. Not to worry! Practise makes perfect!
The course consists of five modules and a final test. In order to graduate, you must score above 70% on your final test. You'll be awarded a PASS, MERIT or DISTINCTION based on your final score.
Each module focuses on a different type of decoder. To become a fully-fledged agent, you'll need to master all five.
Follow the links below to take each module again.
Good luck, Rookie Recruits, and do your best.
