im planning to have a website , where in we are having exercises for our members so when ever a member completed the exercises and goes for submit he will get two icon one is try again or view answers once he clicks on view answers he will not b able to do the exercise again and he can submit his completed exercises where in the correct answers will be rewarded with a point , so whatever is correct he will be rewarded and the same points will be added to his dashboard . The same will be continued for any other exercises or activities in my website.
