GED

I’d suggest doing these:

https://www.khanacademy.org/math/arithmetic (Basic math/arithmetic)
https://www.khanacademy.org/math/algebra-basics (Basic algebra)
https://www.khanacademy.org/math/basic-geo (Basic geometry)

Math is easy, in terms of knowing what you need to know to pass. The other subjects are less clear on what is needed.

For science, I’d suggest familiarizing yourself with the biology and chemistry libraries on khan:

https://www.khanacademy.org/science/chemistry
It looks like the science exam focus on familiarity with certain elements (presumably O for oxygen, H for Hydrogen, and other common elements, less familiarity with other elements), being able to read and understand science articles and use charts and graphs. That sounds less like traditional studying and more like exposing yourself to a variety of sources, and making sure you can interpret what you read and see. Because it says you should be able to use numbers, I’d suggest doing the science after you do math.

For social studies, I’d suggest familiarizing yourself with US history and US government. Like science, it sounds like you need some familiarity, but there’s more emphasis on understanding articles and interpreting charts and graphs. Due to the math involved with charts and graphs, I’d suggest doing math first.

For ELA, there’s a writing component, and khan’s not set up to help with that. Currently, ELA only goes through ninth grade. However, their grammar course is amazing. I’d suggest dojj in g the grammar course on khan, reading comprehension on readtheory, and then google free writing ged for various prompts and their scoring guides. Have someone else score your essays, if possible. You may also want to focus on reading a variety of fiction and nonfiction, focusing on very short stories and articles of different lengths, making sure you understand what is presented.

Good luck!

I would also like to see a GED prep section. Not sure why KA doesn't have one yet, but I wish they did, and I know of so many people who could benefit from it.

Yes, This GED section is  very flexible in KA. I really want to use it for my NWS project.
