Can I transfer from temple to upenn?

Hi so I started off high school really well, 8 credits, no free periods, all honors classes, a couple marking periods I had a 3.9 others a 3.6/3.7. I got an 1960 on the SATs. I took 4 AP classes and got 4s on two of the exams, but As and Bs in all of the classes. But I let my GPA drop throughout high school, which I know is terrible, I just made some mistakes, it doesn’t reflect how I used to be/should be as a student. I wasn’t sure of where I wanted to go to school or what I wanted to major in, but I am now. I have all As so far in my first semester and I want to study history and/or neuroscience. I guess my question is, if I keep up my grades and end the semester with As, as well as next semester can I transfer? And should I apply for my sophomore or junior year? I just kind of ended up picking a school in the area that I wanted to live in and that I could afford, and I like my classes and teachers and all, I just never really liked the area or the campus. I don’t feel comfortable here, like it doesn’t really match my personality? Like I don’t fit in. I was going to go to Drexel but it was just rediculously expensive. I know Penn is a lot more expensive as well but I at least want to try and see where my financial aid offer stands ya know? Also my mom went to school there, I don’t know how much that really affects the decision process, but it would be really awesome if I got to go to the same school as her. Any advice?
