SAT & ACT Math Expert needed to carefully proofread 155 short-style flashcards content

I'm looking for a freelancer with a deep knowledge of SAT and ACT exam requirements and great attention to details. I have 155 flashcards as PDF file that need to be carefully reviewed for any potential errors or improvements. The final accuracy needs to be at the highest level possible, which includes checking the following: -Fact checking -Sentence rewriting for a better understanding - if needed -All formulas needs to be reviewed carefully -Renaming titles, crosscheck titles with content on the backside to ensure title on front matches exactly with content on the back -Review if any concept/formula is not aligned with 2026-2027 SAT & ACT requirements, so needs to be removed -Provide a feedback if any concept/formula is missing in the folder -Label card/files which are strictly applicable for ACT (SAT & ACT are currently grouped together). The final version I expect is to be 100% accurate and structured in the best possible way for students. With this project, I value accuracy more than timeline. The final review summary should be provided in Excel file, including all analysis aspects above. Feel free to ask any question. Best!
