Color-coding of the answers for pretest and posttest pages needs to be fixed.

[shraddha]

Currently the posttest and pretest pages include the following functionalities:

There is a series of questions. Each one of them has 4 answers attached to it. Each question also has a difficulty level assigned. There can be an explanation attached to each answer, or a few one of the answers. The explanation is shown whenever the corresponding answer is selected - irrespective whether it is correct or incorrect.

Out of the 4 answers, only one is right. Initially all answers are of color black.
But once one of them is selected, depending on whether the answer is correct or incorrect, the answer will be colored red (incorrect) or light green(correct). If answer is correct, in the next round, all the 4 answers of that question retain the colors they had before, when one of them became green/correct. But if the answer is incorrect, then the answer should retain the color red until the correct answer is found for the corresponding question.

With the addition of description and difficulty level, this functionality was lost. We need to show the correct answers in light green color.
