Khan Academy is great – I’m using it to relearn algebra and geometry as an adult. Check out r/khanacademy on Reddit, too.

I’ve also found some great free lessons on Youtube. Like, for middle-grade math, try Yaymath. His lessons are fun, easy to understand, and not boring. Mathantics and MashupMath are also good for basic math review. All have humor pitched to middle-school kids, which can be a little weird as an adult, but sometimes I still prefer them to Khan. The last 2 feature helpful graphics and animations.

I also really like Fort Bend Tutoring on Youtube, especially for Algebra word problems. He has a Basic Math playlist that might be a good place to start. He explains everything really clearly and he has a really calming vibe. Krista King is also great that way and has a pre-algebra playlist.

Sometimes I type the Khan lesson title into Youtube and see if one of my favorites has a video on it, then watch that for the lesson instead of the Khan video, just because I like their teaching styles better. The Khan guy can be a little boring. Or I watch both. Then I do the problems on Khan for practice.

I’ve had some test anxiety in the past, although luckily not as bad as you. One thing I have noticed with Khan Academy is that I don’t get as anxious when it’s the computer scoring my work – I guess because I know that it won’t think of me as stupid. Maybe learning online will help your test anxiety, too.

Just this week I signed up for IXL.com to get more math practice problems. You can actually work on the entire K-12 curriculum here online. I don’t know if you can afford it – it’s $10-$15/month, depending on how many topics you study, and they have cheaper yearly plans. But you can also do a small number of free problems on their site each day and look at their outlines for a really good idea of what you need to study. And you could see if your local library has textbooks you can borrow, and work on the problems they have solutions for in the back of the book. You can also get free worksheets with answers here; https://www.kutasoftware.com/free.html .

Also, see this post; https://www.reddit.com/r/bibliographies/comments/36ltzk/math_basic_algebra/

I know what you mean about motivation – that’s really the hardest thing when you are learning on your own. I think your idea to do 2 hours a day is great. (And break that down into 15-20 minute chunks, with 5-10 minute breaks between them to move around/exercise/listen to some music.) Do you think it would help if you joined a GED program? If you call 211 they can help you find a local GED program. Maybe you can even find one that you can do online. Also, check out r/GED and r/GEDPrep.

One thing I like to do for inspiration is watch or read short videos that inspire me to learn more, even if they don’t teach me a specific skill I need to cover. Here are some of my favorites;

• Math : https://youtu.be/ahXIMUkSXX0

• Science : https://youtu.be/BickMFHAZR0

• Tech: https://youtu.be/t4thhWiWnqI

Also see SciShow, Minute Earth, Crash Course, Periodic Videos, TED-Ed, Simple History, It’s Okay To Be Smart, and Tom Scott for more inspiring YT videos.

Good luck to you!

P.S. Maybe try the Grammarly browser extension for English help? “Grammarly isn’t just a safety net. You’ll get detailed explanations for all your mistakes and weekly progress reports to keep you on the ball.”

Then, read some real books, whatever interests you, plus some science and history, then you will be better able to tackle grammar. I would ask in r/languagelearning for some good grammar resources.

A good selection of readings in book form is “High School Subjects Self Taught” by Lewis Copeland, you can get one right now for $7.93 from Amazon:
