LPN STUDENT

Hi, i wanted to know if its only me, i loveee being in nursing school , and i can't wait to start con clinicals which i start next month, but there is something bothering me... I can't concentrate in class i dont know why, i think i haven't learned a thing in 7 months in nursing school, dont get me wrong i have learn simple things but not enough. I am really lost, like if i dont cheat on tests i wont pass the exam, and its rediculous because i love medicine, and i am really smart actually, but i just dont get anything, i dont understand, everything seems so difficult, please help me, tell me how to study, how to learn things, be open minded and ready for the clinicals, i want to learn , i really ewant to learn, i feel so dumb like if i dont know anything, am i the only one? i dont want to cheat i want to be able to pass the exams on my own, another thing is that i have the mental health ATI at the end of this month and im so scared that im not going to pass it. By the way my every monday exam are all based on critical thinking and they are really hard. Please help me and dont judge me . Sorry for the bad spelling...
