I am creating a homebrew class, and am attempting to add a feature that allow you to learn magical secrets. 2 Additional spells at level 1, and anther additional spell at the levels listed. Does anyone know how I can do this?

A am also giving additional sorcery points. an additional 2 at level 3, 6, 12, and 8, Along with the ability to choose one more Metamagic Feature.

There are different ways to do it depending on how you want it handled. Do you want them to have access to all spells? Is it a specific list of spells? Is it a specific type of spells (wizard spells, Druid spells, etc.) that you want to add? A little more specific info and we can definitely help you with that.

As for adding additional Sorcery points... someone may know how to do that, but that someone is not me.

For Magical Secrets, I think you can use the Spells section.
Level Divisor: 2
Consumes Spell Slot: Yes
Counts as Known Spell: Yes or no, depends on your preference.

As for sorcery points, there is nothing that will let you add additional charges to the Sorcery Points feature. You will have to make your own feature that is Extra Points or something similar, and then give it the additional uses / day.
