Laptop for online class

Need help for buying a new laptop. My laptop is fine but, I can't keep up in my online classes. Its always lagging every time I do some Microsoft office stuff like word and excel. I'm a 2nd year University student here in the Philippines and currently studying bachelor of engineering technology. I'm a consistent dean's lister, but I don't know if I can't keep up with my lessons. My laptop was given to me during my 18th birthday last 2017 and it barely keeping up to date. I do a lot of programming for our school and this gave me a problem now cause my laptop keeps lagging every time I run a code in visual studio codes. I tried a lighter IDE like eclipse but it has the same output. One time, during our 'topic defense' for our system development subject my laptop crashed. The panelist and my groupmates waits around 10 mins so I can join to the meeting. I tried finding part-time job and scholarship but due to this pandemic, I can't do anything cause our government sucks at handling the country. I don't really ask for help or any favor, however right now I am very much in need of one. If you guys could please donate any however big or small it would be very much appreciated.

Sharing the link would really help me out so much too, thank you all
