Hello dear student,

It is really simple to analyse where used concepts are not clear. After giving your mock test you can check for the answers of the questions that you have just given in the exam. then you can set with the paper and pen and you can check where you have given the wrong answer and you can write down the topic in which you are failing are not able to score good marks. I hope up that this way you can find your weakness and you can work upon your concepts of that particular topic

Thank you
