ENGINEERING
HELP THAT
HOLDS UP.
Real notes and study systems from a student who earned A’s in these courses—plus an AI tutor grounded in them.
Make the numbers fit.
ISO FIT &
TOLERANCE
Quick reference calculator for common hole-basis fits. Verify critical designs against ISO 286.
Built from the messy middle.
Computer Aided Graphics & Design
Drawing standards, GD&T, datum systems, and submission-ready SolidWorks workflows.
Thermodynamics 1
Choose the right model, navigate property tables, and solve cycles without guesswork.
Engineering Mechanics: Statics
A practical system for free-body diagrams, trusses, friction, and equilibrium.
Mechanics of Materials
Stress, strain, beam loading, and Mohr’s circle made visual and usable.
Programming for Engineers (MATLAB)
Clean starter scripts, debugging help, and plotting patterns for engineering work.
Introduction to Aerospace Engineering
Atmosphere, aerodynamics, performance, and units—the foundations that keep returning.
Ask the course, not the internet.
Each tutor is grounded in the pack you bought. It teaches the method, cites relevant materials, and tells you when the pack does not cover something.
When should I use method of joints instead of sections?
Use joints for forces across much of the truss. For only a few target members, sections is faster. See “Joints vs. Sections Decision Guide.”
