Can my Dr prescribe a memory booster medication upon my request?

I’m a student and I could hardly remember anything after studying. I’m taking a Human Anatomy class and it’s hard for me to focus and to recall everything I’ve learned. I eat healthy food and exercise but this is beyond my control. I don’t trust over the counter medication that boost memory I always feel like they will worsen things.
I’m a hard worker and I’m very dedicated to my studies.even now I’m home studying.

Thanks.
