Khan Academy is excellent for SAT practice and for rebuilding algebra or grammar foundations. It is not an ACT course: there is no official ACT partnership, no enhanced ACT full tests, and no Science section that matches ACT graphs. Use it as a skills gym, then switch to ACT-specific timing and items.
What you can reuse
- Algebra I/II, linear equations, and functions if Math is the hole— then drill the same topics on ACT-style items. How much algebra is on the ACT.
- Basic grammar videos as a second explanation after you miss an official English question. Rules hub: ACT English grammar rules.
What Khan will not do
- Time you for 50 English questions in 35 minutes
- Give four long ACT Reading passages with nine questions each
- Train ACT Science figures-first strategy
- Produce a 1–36 Composite with a real conversion table
