Science Tutoring By Course
Pick the class you're taking now. Every course starts with a free 45-minute trial session.

Tutors Who Know The Lab
Every Brennock tutor has a degree in chemistry, physics, biology or engineering, and most have worked in a lab or a plant. They know which ideas the rest of the course is built on, and they can show your student why the formula works instead of asking them to memorize it.
We match each student with one tutor for the whole year, so nobody has to start over explaining where they're stuck.
- ✓Science or engineering degree, every tutor
- ✓The same tutor all year
- ✓Studio in Katy or online
The Topics We Untangle Most
Moles And Stoichiometry
The unit where chemistry turns into math. We teach it as a recipe before the formula.
Forces And Free-Body Diagrams
Draw it right and the physics problem solves itself. We practice the drawing first.
Equilibrium
Reactions that go both ways, explained with pictures before ICE tables.
Lab Reports
Clear methods, honest error analysis and graphs that show what happened.
Science Specialists, Nothing Else
Science Only
We don't tutor English or history. Every session is chemistry, physics or biology.
Why Before How
Students learn where each equation comes from, so they can rebuild it on a test.
Practice That Matches Class
We work from your teacher's syllabus and the unit you're in this week.
Notes After Every Session
A short summary for parents: what we covered, what's next and what to review.

Science Tutoring FAQ
How much does chemistry tutoring cost?
$80/hr for high school chemistry, physics and biology, $95/hr for AP and honors courses, $110/hr for college general and organic chemistry, and $125/hr for MCAT science. The 45-minute trial session is free.
Do you tutor in person or online?
Both. Our Katy studio is open Monday to Thursday afternoons and evenings and Sunday afternoons, and online sessions use a shared whiteboard.
How often should my student come?
Once a week works for most students. We suggest twice a week for a few weeks before a big test or when a grade has dropped quickly.
Can you help with college chemistry?
Yes. General and organic chemistry are two of our busiest courses. Bring your syllabus and problem sets and we'll work from them.
Will tutoring raise my grade?
Most students see their understanding improve within a few weeks, and grades usually follow, but no tutor can promise a grade. We'll tell you honestly how things are going.
What if the tutor isn't a good fit?
Tell us and we'll match you with someone else. There are no contracts, and you pay per session.
