ACT Science Prep Classes
Short-term classLiveMedical Mysteries & Rare Conditions
Being a doctor involves a lot of detective work: symptoms make for good clues, but people often don't do a great job of describing them and even when they are, the clues don't always point to one clear suspect or diagnosis. That's why students love Medical Mysteries & Rare Conditions, a chance to learn a bit of biology through the lens of a doctor detective. Over four weekly sessions, you'll join Dr. Tabitha Michaud to learn to think like a doctor as you learn about types of symptoms, causes, and cures, and put your symptom sleuthing skills to the test to diagose, treat, and understand rare illnesses.
Short-term classLiveHigh School Biology Fundamentals
High School Biology is the study of the building blocks of life, how cells, systems, and processes interact to enable complex organisms to adapt and thrive. And just like living systems build from their foundations, your own biology knowledge builds concept by concept toward the complex skills you need for your labs and exams throughout the year. That’s why High School Biology Fundamentals is an integral component of your biology studies. Each week, an expert instructor will break down the key concepts that your current and upcoming biology lessons depend on, helping ensure that you’re ready for the challenges you encounter in your coursework and your foundations remain strong for midterm and final exams, cumulative assignments, and even future science classes.
Short-term classLiveHigh School Chemistry Fundamentals
Much like chemistry itself is the study of how the building blocks of matter–particles, atoms, molecules–combine, your chemistry knowledge builds from basic elements toward complex concepts, lab reports, and exams. That’s why High School Chemistry Fundamentals can be an integral force in your chemistry studies. Each week, an expert instructor will break down the key concepts that your current and upcoming chemistry lessons depend on, helping ensure that you’re ready for the challenges you encounter in your coursework and your foundations remain strong for midterm and final exams, cumulative assignments, and even future science classes.

Frequently Asked Questions
ACT Science gives you 40 questions in just 35 minutes—roughly 50 seconds per question—which is notoriously tight. The challenge isn't just speed; it's knowing which questions to tackle first and which passages require deeper analysis versus quick data interpretation. A tutor can teach you to quickly identify passage types (data representation, research summaries, conflicting viewpoints), prioritize easier questions, and develop a personalized pacing strategy that matches your reading and analysis speed, helping you avoid the common trap of running out of time on the last few questions.
ACT Science features Data Representation (graphs, tables, diagrams), Research Summaries (multiple experiments with methods and results), and Conflicting Viewpoints (two or more opposing scientific perspectives). Each requires a different strategy: Data Representation focuses on reading charts and extracting specific values, Research Summaries demands understanding experimental design and comparing results across trials, and Conflicting Viewpoints tests your ability to identify key differences between positions and evaluate evidence. Tutors help you develop targeted techniques for each type so you're not using a one-size-fits-all approach that wastes time.
Many students assume ACT Science is purely about scientific knowledge, but it's actually about data interpretation and reasoning—content knowledge matters less than you'd think. The best way to pinpoint weaknesses is to take practice tests under timed conditions, then analyze your wrong answers by passage type and question category (rather than by biology, chemistry, or physics). A tutor can help you spot patterns: Are you missing questions because you misread the data? Do you struggle with certain graph types? Are you getting tripped up by the conflicting viewpoints section? Once you know whether your issue is speed, comprehension, or reasoning, you can focus your prep strategically.
Not necessarily—ACT Science reading is fundamentally different from ACT Reading. While good reading skills help, ACT Science prioritizes extracting specific data points and understanding relationships between variables over comprehending narrative or argument structure. Many strong readers actually over-read the passages, wasting precious seconds on details that don't matter for the questions. Tutors teach you to skim strategically, identify what information you actually need to answer each question, and resist the urge to fully understand every detail of the experiment or data set before diving into the questions.
Score improvement depends heavily on your starting point and consistency. Students who struggle with pacing and test strategy often see 3-5 point improvements (on the 1-36 scale) within 4-6 weeks of focused work, since they're fixing technique rather than learning new content. Students starting from a higher baseline (30+) typically see 1-2 point gains, as they're refining nuanced reasoning skills. The key is consistent practice with real ACT tests, targeted feedback on mistakes, and deliberate strategy refinement—tutors accelerate this process by pinpointing exactly what's costing you points and helping you practice the right way.
ACT Science's brutal time pressure naturally triggers anxiety, which often leads to rushed reading, careless mistakes, and decision paralysis on harder questions. Unlike other sections where you can slow down and think deeply, Science forces you to make quick judgments with incomplete information, which can feel chaotic under stress. Tutors help manage this by building confidence through repeated exposure to real test conditions, teaching you to recognize when you're overthinking versus when you genuinely don't know an answer, and developing a pre-test routine that keeps you calm. Practicing with actual ACT Science passages under timed conditions is one of the most effective ways to reduce anxiety because you're literally training your brain to handle the pressure.
Conflicting Viewpoints is the most content-heavy passage type and requires you to track multiple perspectives, identify where they agree and disagree, and evaluate evidence—all while managing time pressure. Students often get confused tracking which scientist or theory supports which claim, or they spend too much time trying to decide which viewpoint is actually correct (which doesn't matter for the test). The questions typically ask you to identify implications, predict outcomes under each viewpoint, or determine what evidence would support one position over another. Tutors teach you to create a simple comparison chart as you read, focus on the specific differences between viewpoints rather than the full details of each, and practice the unique question types that appear in this section.
Quality beats quantity: one full, timed 40-question section with detailed error analysis is more valuable than doing multiple untimed passages. After each practice session, categorize your mistakes—did you misread data, misunderstand the question, run out of time, or lack content knowledge?—then review only the passages where you made errors. Use official ACT practice tests rather than third-party materials, since the real test has specific quirks in how it presents data and structures questions. Between tutoring sessions, focus on the specific passage types or question formats your tutor identified as weak points, and time yourself ruthlessly to build the speed and accuracy you need.
