NUSWhispers – Confession #50405

Being a non-math major, how hard will one find MA3218 - Applied Algebra ? I am a CS major and want to take this course to further take MA4261 - Coding and Cryptography. Also wanted to know if the lectures of this module are webcast or not ? I have no good reason to go anonymous in this post other than the fact that NUSWhispers is hopefully read by a lot of students who took this course in past.
