Colorado public high schools give the PSAT in 9th and 10th grade and the SAT to every 11th grader during the school day, so the ACT is not part of the school calendar here. Denver families who choose the ACT plan around a test date the school is not setting for them. We help students prepare for it in 1-on-1 sessions, never a group class.
We tutor the ACT in person in Denver, Greenwood Village, Cherry Hills Village, Highlands Ranch and Littleton, and online for families anywhere else. Your first hour of tutoring is free. After every session, the tutor writes feedback on what was covered and what's next, so you can follow your student's progress from week to week.

The ACT changed in 2025. The enhanced ACT is shorter, gives students more time per question, and makes Science optional. Your student's Composite score (1 to 36) now comes from three sections: English, Math, and Reading.
| Section | Questions | Time | Counts toward the Composite? |
|---|---|---|---|
| English | 50 | 35 minutes | Yes |
| Math | 45 | 50 minutes | Yes |
| Reading | 36 | 40 minutes | Yes |
| Science (optional) | 40 | 40 minutes | No. Adds a separate STEM score |
| Writing (optional) | 1 essay | 40 minutes | No. Adds a separate ELA score |
The three core sections take 125 minutes. A few changes worth knowing:
Our tutors build each student's plan around the sections they will actually take.
Science. Since Science no longer counts toward the Composite, most students can skip it. It is worth taking when a college your student is considering asks for it or values the STEM score, or when your student is aiming at a STEM program and wants that score on record. Despite the name, ACT Science is mostly about reading charts, graphs, and experiment summaries quickly, not about memorized science facts.
Writing. The optional essay produces a separate ELA score. Few colleges require it today, so most students skip it unless a specific school on their list asks for it.
Our advice: decide based on your student's college list, not on a guess. In your free consultation we look at that list together and build the plan around the sections that matter. If your student takes Science or Writing, our ACT program covers them too.
On a free 30-minute call by phone or Zoom, we review your student's starting point, goal, test date, and schedule, then recommend a program.
Your ACT tutor uses full-length practice tests to see exactly where points are slipping and which skills will move the score most.
One-on-one sessions target the highest-impact skills, and regular practice tests guide adjustments. After every session, your tutor writes feedback on what was covered and what's next.

Yes. A test prep package is a commitment to the hours you buy (see our program terms). That's why we start with a free consultation and a free first hour, so you can be sure before you commit.
No. The weeks shown are typical, not deadlines. Sessions are scheduled around your student's calendar and test date, and you can reschedule for free with at least 6 hours' notice.
Keep unused hours as store credit at your package rate, or take a refund: we re-price the hours you used at the rate they qualify for (a smaller package or pay-as-you-go) and refund the difference.

View Profile →I took their ACT prep course and they helped me raise my score from a 26 to a 33! They knew exactly what I needed to practice and my tutor was outstanding. When I saw my score I was nearly in tears. I'm confident the change will be the difference between acceptance and rejection at my top-choice college.
We've used High Performance for two years. Victor helped my son with Chemistry, his grade went from a D to a B+, and he ended up liking the class. They've also tutored him in Algebra and for the ACT. They genuinely enjoy working with the kids, and the kids enjoy working with them!
Calling High Performance Tutoring was one of our best decisions after treading water with other options for our daughter's ACT. My daughter jumped 6 points on the ACT and felt great about her improvement. We'd highly recommend them for a motivated student eager to improve!
My daughter Hannah raised her ACT score from a 26 to a 33 after completing an intensive twelve-week training program with High Performance Tutoring. This score will open up so many doors for her!
Gopi is an amazing tutor, my son's ACT score went up 6 points, from a 28 to a 34. Thank you!
I've worked with Victor for over a year and I'm beyond satisfied with his expertise. He explains very thoroughly, and in a way that sticks! All A's on tests I study with him for. Highly recommended for subject tutoring and SAT/ACT prep.
David took the ACT and SAT each only once after his tutoring, and he was accepted to Harvard. We'd love your very best tutor for our youngest now.
We've been very impressed with the methodical, detailed tutoring by Ingo. He's been working with our son on his SAT and ACT prep. Extremely pleased so far!
My children have loved every tutor we have used from High Performance. The tutors have helped them excel in their studies in the classroom and helped them succeed on the AP, IB, ACT, and SAT exams!
A belated thank you to Liz for a semester of math tutoring. She essentially taught all of Algebra Honors II. My child received an A in the class and scored in the 99th percentile of the PSAT. We could not have done it without your kindness and teaching skills!
Liz is the best. Ethan learns so much with her, and we love how flexible her schedule is.
[Our student] loved Victor's energy, knowledge, and approach. We're excited to sign up to give [our student] additional support.
Most students take their first ACT in the spring of junior year, which leaves time for a second attempt in the summer or fall of senior year. Starting prep two to three months before the first test date is a good rule of thumb, and earlier is better for students with a big score goal or a busy junior year. Because ACT superscores the core sections, a second attempt can focus on the one or two sections with the most room to grow. Our article on the scoring trick that turns one bad section into a free retake explains how.

It depends on your student's strengths and practice-test results. In your free consultation, we can discuss ACT and SAT fit, timing, and goals before recommending a plan. Should my child take the SAT or the ACT?

Colorado schools build their testing schedule around the PSAT and SAT. Here is how the ACT fits alongside them.
Students take the PSAT at school in 9th and 10th grade. Those scores can be a useful starting point before deciding on the ACT.
See PSAT in 9th and 10th Grade →Every 11th grader at a Colorado public high school takes the SAT during the school day. Some families prepare for that test alongside the ACT.
See SAT in 11th Grade →Since the ACT is not given at school here, your student picks a test date that suits them, and we plan the tutoring sessions around it.
