We have given two different levels of exercises. The second level of exercise belongs to some questions along with four similar hints where user has to click on the box with correct answer. The score keeps on adding with an increasing number of correct answers and empty box is filled with a green colour. Otherwise, red colour symbolizes wrong answer. If in case, user clicks on the wrong answer, there is a provision of multiple clicks unless right answer is detected. Finally, the user can have an opportunity to self-evaluate through the scores that will be displayed in the score board.
