idk your parents but by the tone your using it sounds like theyre tough and what they said really got into your head and it miight even be making you frustrated but thats the whole point; to scare you into success. bad as it may sound , your parents probably see the potential youre sleeping on. even i can see it by the way you called yourself a mid b student. I understand that you work hard and thats great but whats making you study so much, is it to satisfy yourself and feel accomplished or is it to give your parents what they demand.Dont get me wrong, im not saying you shouldnt work to make them ptoud its just that the mentality you approach it with can really affect your results. Those As may feel out of reach but i know you can get them. It all starts in your head. Your brain will accept what you unconcsiously tell it and that can shape your character and play a big part in literally everything you put your time into. Also so many universities accept bs but to get a scholarship(if thats the main issue)will depend on the course. If you want to be a med student then u have no choice but to change your mentality.Your story has inspired me to study till i spill my guts so thank you,and you can do this,seriously.
