Division of problems by difficulty level

When the editorials are published there are 5 kind of divisions for difficulty level :
1. Cakewalk
2. Simple
3. Easy
4. Medium
5. Hard
However , when the problems move to practice section the first three categories are combined in EASY . I dont like this . I have been a computer science teacher in past and still some people come to me for guidance . Its difficult for me to guide them to code chef because there is a wide range of problems in EASY section . Some are cakewalk which is where i want them to start . But some are in fact quite difficult and EASY only for someone who has completed his computer science education not for someone who has just begun his computer science section .
Now with School section coming up there is a new category in practice section . I dont think it serves any good to have a separate "School" category in practice section . They should also be categorized into 1 to 5 difficulty level and marked as such .
