Your freshman course is the material you've already met.
College Algebra is Algebra 2 under a new name. General Chemistry is the course AP Chem was built to match. LessonSlate already teaches all of it — so when the lecture moves too fast, you can watch someone reason through the exact problem, as many times as you need.

You're not starting over — you're reviewing
The intro college sequence covers the same skills you saw in high school, just faster and with less hand-holding. Here's how the courses line up.
AP Chemistry is designed to be equivalent to a two-semester introductory college chemistry course — which is exactly why so many colleges grant gen-chem credit for it. The material isn't new to you; the pace is.
Made for the college moments
Not a full course to sit through — a lesson for the exact problem type that isn't clicking, right when you need it.
The lecture outran you
The professor worked it once at full speed and moved on. Re-watch a student hit the same wall and get unstuck — pause and replay as often as you like.
Midterm in three days
Cram by problem type, not by re-reading the textbook. See the reasoning and the common wrong turns for the shapes that'll be on the exam.
Placement & readiness tests
Brushing up for a College Algebra placement or an ALEKS-style test? Refresh logarithms, functions, and rational expressions before you sit it.
Retaking a course
If gen chem or college algebra didn't go your way the first time, target the specific topics that tripped you — calmly, on your own schedule.
Summer bridge before freshman year
Get ahead the summer before college. Walk into your first gen-chem or algebra lecture already familiar with how the problems are solved.
Office hours are booked
When the TA line is long and it's late, a patient lesson that never gets impatient is the next best thing to a tutor.
Subjects available now
Live today — with the intro college course each one maps to.
Stoichiometry, thermochemistry, kinetics, equilibrium, acids and bases, electrochemistry and more — spoken in real notation, with Sam and Dr. Chen.
Complex numbers, logarithms, exponentials, polynomials and rational functions — every ± and asymptote drawn out on the canvas, with Naomi and Ms. Rivera.
The foundation a lot of college math builds on — equations, systems, quadratics, functions and word problems, with Maya and Ms. Rivera.
Angles, triangles, circles, area and volume, coordinate geometry and proofs — the groundwork for trigonometry, with Cody and Ms. Rivera.
The messy middle is the part lectures skip
A lecture usually shows the clean solution once. But the useful part is watching where a real person hesitates, guesses wrong, and corrects — because that's where your own confusion lives too. Every LessonSlate lesson keeps that in.
- Reason through a problem at your own pace, on repeat
- See the common wrong turns before you make them on the exam
