Laptop Recommendations Refurbished BackMarket | $350 max | United States

Hello, I am looking for a computer for university that would ideally take me through 4 years + medical school. I typically use BackMarket for computers, but I am having a hard time finding one, as I have little to no knowledge in this space. I really appreciate any and all help/advice! Thank you!

LAPTOP QUESTIONNAIRE

• Total budget (in local currency) and country of purchase. Please do not use USD unless purchasing in the US: $350USD in the United States.
• Are you open to refurbs/used? Yes!
• How would you prioritize form factor (ultrabook, 2-in-1, etc.), build quality, performance, and battery life? Performance, battery life, and then other
• How important is weight and thinness to you? Not important
• Do you have a preferred screen size? If indifferent, put N/A. Around 13inches would be nice
• Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. MatLab. I am currently taking an engineering class, but am going more premed, so I will not be continuing that after this semester.
• Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? Preferably Windows (Definitely not Apple) and touchscreen
• Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion. I was looking at a computer like this one, but was concerned that the GHz processing speed is too low for the RAM and storage?
