What would be the best purchase for a Pre-Health/Med School student?

I am currently a Junior in college and I am a Biology major/Chemistry minor. I have an older Windows laptop (Dell Inspiron 2017 15 5000) which is beginning experience slow loading speeds and experiencing difficulty loading documents. It has become a hindrance in my schoolwork where I have to wait for several minutes for a simple Word document to load.

I've decided to make the switch to Apple computers because my girlfriend and the rest of my family who use MacBooks and have told me that they are great to have for school because the have a longer battery life, faster load speeds, and better displays than my current laptop. I also have decided to make the switch because of the amazing ecosystem between all of their devices, connecting my iPhone 8 Plus, Apple Watch Series 3, and 1st Generation Airpods seamlessly. I find that these are the two main reasons that I plan to purchase an Apple computer.

As much as I would like to have a MacBook Air, I am afraid that I may not have the money to purchase one before the school year begins. As a result, I began to research iPads, where I have noticed that they are becoming more capable of becoming a suitable replacement for a laptop. My girlfriend also uses an iPad to take notes on for classes and she tells me that it is the best way to take notes in college, which has made me think of the versatility of using an iPad for my schoolwork.

As I conducted my research, I discovered the "Back to School" promotion that Apple does every summer before the school year begins, so this will knock off $100 from Macbooks and iPads and will grant you a pair of discounted Airpods with your purchase. As a "broke college student", I try to take advantage of these types of deals.

So, my question is: "What is the best Apple purchase for a Pre-Health student?"

I am looking for a "budget" Apple product to serve as my daily driver laptop for the next 4-6 years as I finish my education. I plan to spend no more than $1,400 on my purchase. I feel like I should reiterate that I am a Biology major on the Pre-Med/Pre-Dent track.

Below are three options that my father, my girlfriend, and I came up with for my next computer purchase. Feel free to leave your own recommendations as well (I am open to all suggestions).

My first option is the 2020 MacBook Air with the 1.1 GHz quad-core 10th Generation Intel Core i5 processor with 8 GB of RAM and 256 GB of base storage (and obviously Apple Care). This would come with Airpods Pro for an additional $90, with a total of $1,394.26.

My second option is the Space Grey 2020 iPad Pro with 256GB of base storage and only Wi-Fi (again with Apple Care), the 2nd Generation Apple Pencil, the Smart Keyboard for the iPad Pro, and the Airpods Pro, for a total of $1,428.90.

My third option (the cheapest) is to go with the 10.5 inch Space Grey iPad Air (Wi-Fi only, 256GB storage) and with Apple Care, as well as the 1st Generation Apple Pencil, the Smart Keyboard for the iPad (7th generation) and iPad Air (3rd Generation), and the Airpods Pro for a total of $1,095.49.

Thank you for your help!
