Achievement System

[andreidimaano]

Users want to see their progress/level up.

Implement a leveling system based on time spent studying.

• create an algorithm to determine all-time leaderboard

It'd be cool to see both a weekly leaderboard and also an all time leaderboard!

One way to begin would be with daily user stats over currently employed accumulative style that shows total hours studied. A daily hour count will make levelling and leaderboard features neater looking too.
