Here are links to the Grade 11 and Grade 12 Monogame Lessons.
In grade 11, you will be introduced to Monogame for the first time and have a slower and thorough progression through the basics of programming with graphics.
Since you used Monogame in grade 11 already, this is a quick recap with some more advanced concepts related to making larger more complicated games.

Here is a link to where you can find tutorials made my other people and myself. Keep in mind that there often many different ways to do the same thing, so you may see tutorials that cover the same topics, but vary in how they achieve the same result.
