When I presented Real Not Complex to the first users, there was one feature that was suggested over and over again. And now that feature is here! In order to easily browse all the resources available on our website, it's important to quickly get an idea of how good and how accessible is given resource. This is precisely what our grading system was created for, allowing you to find trully incredible free math resources even easier than before.
There are two things that we want to know about a textbook, lecture notes or video lectures, when we learn a new topic in mathematics:
These two aspects are the most important for studying and we that knew we have to include both of them in our rating system. After all, we all have seen simple, but low quality textbooks, as well as difficult, but great ones (Baby Rudin anyone?).
But we also did not want to complicate things further, so we decided to go with the most basic, 3 step rating system, represented as stars:
So when you learn a new topic, you will probably want to look for resources with 3 stars on quality scale and 1 star on difficulty scale.
If you however want something challenging or review material, you will look for 3 stars on quality scale and 3 stars on difficulty scale.
And that's basically it!
I would like to invite all of you to vote on the resources you already have an opinion on. This will help other users discover incredible resources, allowing them to easily learn even the most challenging topics.
