There are two versions of the Surface Go. One of them only has 4 Gb of RAM, and so barely reaches the current minimum specifications for MATLAB. The other one has 8 Gb of RAM, and so is plausibly useful for MATLAB.
I did a lot of productive work with MATLAB in 8 gigabytes of RAM. However, I was getting increasingly frustrated with having only 8 gigabytes. MATLAB was increasing in size, the operating system was increasing in size, the number of operating system daemons was going up, browsers were increasing in size, the amount of data I was trying to handle at the same time was increasing, I was running more simultaneous Maple windows computing things for MATLAB users, I was running virtual machines so I could run MS Windows on my Mac so I could answer Windows-specific MATLAB questions (or so I could help administer my mother's Windows system)...
These days I would no longer purchase a new system with as low as 8 Gb for more than casual MATLAB use.
However, if your intended use is just school assignments, then 8 Gb might work fine for you for a few years. By the time of final year projects, it is a bit more difficult to predict whether it would be enough or not.
If you are thinking of it as a longer term system, then I would not purchase the Surface Go. It is only dual core 1.66 GHz.
Oh wait, major problem: The Surface Go runs Windows 10 S, and "Rather than allowing you to download and install whatever you feel like, Windows 10 S Mode will only permit apps from the Windows 10 Store to be installed. " MATLAB is not in the Windows 10 Store, so you would not be able to install it -- not unless you switched out of Windows 10 S mode, which is not currently permitted (but is in the works.)
