I have given up computer science. Here is why?

An average high school student knows computer science better than me. I’m below average in Computer area even I spend 10 hours to study computer science every day. I cannot learn computer. I learn medical term in just 5 minutes. I’m not interested in medicine but it is better choice for me. I’m a high school student and even I study the computer relevant things in university, I think I should get the lowest mark in the department. I only failed the input / output test in the class. I spend 10 times more hours to Computer science than swimming but I’m better in swimming than computer science. @Lost_N_BIOS
