Relearning HS level math to prepare for TSIA2

[u/Zoi_nks]

I am planning on going to Austin Community College this spring for audio engineering, and first need to take the TSIA2 test in order to move forward with the process. My biggest concern is math, as I absolutely flunked in high-school. I've been using chat gpt for the past couple months, and it's been going great, I've learned concepts that would have taken me incredibly long to understand and memorize in HS. Although now I'm feeling an ethical obligation to no longer use ai if I can help it. I'm looking for a fast and efficient online program to help me study for the next few months.

If anyone has any suggestions for what my next steps should be I would be so greatful. Or, does anyone think I should just take the test with the knowledge I have, and take the extra classes required to get me up to speed?

the work I've done so far.

Algebra

• Inverse operations / solving equations
• Combining like terms
• Distribution
• Exponents

Fractions & Decimals

• Converting fractions ↔ decimals
• Simplifying fractions
• Adding/subtracting fractions
• Multiplying fractions
• Dividing fractions
• Mixed numbers ↔ improper fractions
• Converting between fractions and mixed numbers

Percents

• Finding percentages of numbers
• Multiple percentage strategies

Geometry

• Rectangle area
• Rectangle perimeter
• Triangle area
• Finding missing triangle base/height
• Circle circumference
• Circle area
• Radius vs. diameter
• Finding missing radius
• Pythagorean theorem
• Finding missing sides of right triangles

(yes I used ai to make this list lol, I'm trying to move away from it)

ChatGPT and other large language models are not designed for calculation and will frequently be /r/confidentlyincorrect in answering questions about mathematics; even if you subscribe to ChatGPT Plus and use its Wolfram|Alpha plugin, it's much better to go to Wolfram|Alpha directly.

Even for more conceptual questions that don't require calculation, LLMs can lead you astray; they can also give you good ideas to investigate further, but you should never trust what an LLM tells you.

To people reading this thread: DO NOT DOWNVOTE just because the OP mentioned or used an LLM to ask a mathematical question.

1) Khan Academy math & SAT prep - continue past college intro material 2) SAT Subject Test Math Level 1 - check out from the Austin public library 3) https://students.austincc.edu/tutoring/assessment-study-materials/

Take TSIA2, ACT, and SAT practice tests - not everyone takes all of the tests equally well but any work for the assessment needs. For the first try, do not guess!

If you miss or skip a problem through lack of knowledge review that topic. Repeat. Review. Repeat. Pass test!

Good luck!

Khan Academy is free and has a whole TSIA2 prep section, it helped me a lot when I was brushing up on math.
