I am a bsc 2nd year student . I goto college and also teach biology and science. You May find my age less and not suitable for your child in aspect of knowledge but what can be a better benifit to student th an this that his /her has also faced same problems and same time period in the same books what he/her facing now .it only helps to break the hesitation between teacher and student and teacher becomes good motivator too. I am also trying same here to make study easier than they thought. + more - less
