Hi,
I must say, I'm a senior software engineer at E-Learning company. I have extensive knowledge developing web based quiz systems with MCQ, Short Answer, Matching etc. I certainly think Im the right guy
From what I understood you need a working prototype, which I can provide within a day. My plan is to implement a 60 mcq (questions can be added and removed) with optional timer, marking the correct answer upon submitting and review option. If you need anything else let me know I can include them as well.
Depending on your preference I can either use JQuery or JQuery+Angular for front end along with twitter bootstrap.
Best thing is I have already done these so I know about standard formats (standard quiz formats like GIFT, Blackboard, Moodle), I have pre built components. So would be easy to get started asap (without any R&D)
Later we can integrate randomizin, stratified randomizing, shuffling as per your requirement
Looking forward to work with you
Thanx
