Parents & Childrens are FOOLING each other

How parents & childrens r fooling each other when it comes to NEET/JEE preparation 

Parents know very well that their child is not capable of cracking these exams with desired marks,still they admit them to one of those courses just to keep their child happy & motivated .

Similarly,
The child too knows his capacity,but to keep his/her parents happy the child himself gets enrolled in such courses ! 

Such confusions can be avoided if child & parents talk openly about it to save hard earned money of parent & precious time of students
