I, absolutely, love my large iPad Pro for creative sketching/drawing/illustrative work. I, also, use mine as a laptop replacement for writing notes and quick sketches, typing texts and for other entainment and reading purposes, too!
I am not sure how well iPads do in an educationa/college setting and I am not sure how well it will fare for your medical major, either.
iPads and iOS use scaled down, less feature rich applications than the ones typically available for a normal laptop/desktop computer.
And with iPads and iOS, just about every major tasks you will need to do on an iPad will need its own app where you might be importing/exporting data back and forth through these apps to get the completed task done.
You need to use an iPad in a different way from a normal computer.
That stated, instead of getting the Apple Smart keyboard cover (with the Apple pencil), get the Logitech iPad Pro keyboard case, instead.
Logitech's keyboard is a superior keyoard case to Apple's own keyboard cover, with more keys that are, also, backlit for better visibility in darker environments.
If you decide on the larger, 12.9" screen iPad Pro model, go for the highest 256 GB storage capacity.
The 32 GB storage models (approx. 26 GBs actual data storage space) models are barely adequate for storage of both apps and data and really don't allow for enough wiggle room for free data storage space.
I own the 128 GB storage model (approx. 117 GBs actual free storage space) and while this has been working out just fine for my iPad use, it was the highest storage limit back last Nov., but I like to have the highest storage limit to make sure the iDevices I put to constant use everyday have more than enough needed storage for "future proofing" as I keep my iDevices for more than 4-5 years before replacing them with the newest iDevice available at that time.
In any event, make sure you purchase extended AppleCare for the mobile computing device you end up purchasing.
Also, if you decide on an iPad Pro, make sure you have something or some way to make consistent and reliable backups of the data on a Apple iDevice.
Apple's iDevices are less mature, robust and more fragile devices when it comes to storing important data for the long term.
If you decide on an iPad/iPad Pro, you need to get some sort of local, portable, external storage device to make backups of data stored on an iPad.
Look to something like the SanDisk iXPand Flash Drives for iDevices. Get one that,in a storage size that is, at the very least, half the data storage space size of your chosen iPad data storage size.
Good Luck on whatever you decide.
