If your physics is really good, then your IQ is no problem. If math is not good, how can physics be good? Chemical calculation will not be very good, and biological calculation should not be particularly good. The other three are good, and math is not bad. Maybe it's your study method, the wrong angle of thinking and the wrong way of thinking. You can talk to the teacher. If you can't find the problem yourself, let the people around you help you. The authorities are fascinated by the beholder! Good luck!
