What is the highesy GPA I can obtain this semster?

The end of the semster is approaching and I am a second semester sophomorr in high school. I am enrolled in six classes. I am taking 5.5 credits. Three of the classes are AP (an A is weighted 5.0, B: 4.0, and so on). 3 are regular (one is required to graduate) (an A: 4.0, B: 3.0, and so on). I currently have a 3.789 GPA and have 5 As and 1 B. The 1 B is the regular class and I have all As in the 3 APs and other regular classes. My question is what is the highest I can bring my GPA up to this semester? (If it’s needed: I took 5 classes Freshmen year) Thank you, I appreciate your help!
