Brah I cant do this anymore

My sister went off to go to college and we dont call or talk often but anytime we get to call instead of actually having a conversation about how she's doing she just tells me I have to get a 1400-1500 on my sat and I need to study, do duel enrollment, etc. Everytime we talk its just about college. I just want a normal talk but everytime its just about studying. Im a sophomore and I get I have to study and work hard but is it that bad I just want one normal conversation with my sister without getting this drilled in my head? I feel like im never good enough and I just want to be happy. I dont want to let them down but I dont think Im all that smart enough to fit their expectations. It hurts
