ACT Advice

I recently signed up for the July ACT. I had some questions regarding how accurate the official practice test was. Are scores similar? If not, are they higher or lower? Can I use Khan Academy as practice and use ACT practice tests? I’m really hoping the test is not cancelled like the June SAT. Thank you!

I used Khan Academy to study for the ACT and it helped me raise my score from the practice. Ultimately, my SAT was better for my schools.
I didn’t use the ACT practice tests other than the PACT, but I only took the ACT once so I’m not sure of the accuracy since my score raised bc of studying.
