Review on CALF by Elton Luo

The best thing about this software was that I could see my students' progress, even when they were offline! This helped me track their performance much more easily than any other system out there (I used to have an excel spreadsheet which didn't work very well). It also allowed us teachers greater freedom because we no longer had "the boss" looking over our shoulders all day every single time something went wrong - instead he/she just got emails from people who needed help solving problems like homework assignments etc., rather then having someone call them repeatedly until you did get through at 3am one morning so late into what should be sleep hours anyway? And if anyone's ever been sick during summer vacation while using Calf before school started again...well let say things weren;t going too smoothly but after getting back online everything worked perfectly fine without anything extra being done by myself since everyone else knew how exactly where each student.
