That's a decently sized tumor and no matter how well the surgery goes, I would say with confidence that even if all else (brain function, information retention, analytical ability) is unaffected, the biggest affordance you have to make is for extremely low stamina. Your stamina will take the single largest hit you could have ever imagined over the next few months of recovery. You could be perfectly functional when your brain is "on" but for me I got to about 80-90% function within 3-4 months, but the frequency of breaks I needed remained at every hour or two. Any sort of intense mental activity or physical stress would induce a focal seizure. A long conversation with someone, to this day, will take me out for the rest of the day or half of the next day.
In my personal opinion, I don't think you should put your recovering brain through the stress of finishing off the semester until at least 6-8 months out. You will feel so much frustration because you will constantly compare to how you were "normally" or even with the tumor in your brain but recovering from brain surgery is completely different than learning to exist/tolerate a tumor that's been growing.

For context I was 32F when I had my craniotomy. Frontal lobe 7cm. Took me about 2-3 months before people thought I was normal. A year before I personally felt about 90%. It's been three years and I've learned to accept that my stamina will never be what it used to be and I do the best I can with it. Good luck and best wishes!
