The following repository is not aimed to teach MIPS assembly language, instead has multiple practice problems students can refer to.
For those in university or anyone who wants to learn MIPS programming language, I can recommend book "MIPS Assembly Language Programming" by Robert Britton
All MIPS programs can be run using "Mars simulator"
