Project done for a client

Projects are tacks that shows your ablility(ies) in some thing you  love doing, most especially if you are tested and trusted.  There is a key differences between “doing projects” and project-based learning!
When we engage in a task actively either group of individual with a lasting solution to an issue of problems, that's a "doing project" 
But Projects-based learning (or PBL if we prefer!) will be more successful when collaboration is not only encouraged but built in. All parties must be involve in this.
