Need advice on if I should change my freshman first semester college schedule please

I’m taking five classes (15 credits) and my mom thinks I should only take four. One of my classes (gov and politics) is only once a week though. She wants me to drop my design symposium class, I don’t want to drop it without talking to a counselor first because I didn’t make my schedule my school made it for me. Also they gave me an earth science course and I went on rate my professor and this teacher has forgotten to post grades and messed up students gpas, should I try to change the class to a math class. I prefer math to science any day. I don’t know if it looks bad me trying to change my classes so early on before school even starts. I’m a political science major by the way, incase that matters in this question. Thank you for any advice you can offer. The science teacher doesn’t sound too bad but I have to maintain a certain GPA for the grad school I want to go to so I don’t know if I should risk it.
