How it works

Say what's hard
Type it or say it, the way you'd tell a friend. “k map”, “demorgan”, “the mux thing” all work.

We trace the roots
RootCause walks back through the prerequisite graph and checks your scores at every step to find the weakest link.
- Flip-Flops 30%
- SR Latch 42%
- De Morgan's Theorems 35%

Fix it in 3 days
A plan that starts at the root, with notes for every topic. A 3-question check updates your memory and the plan moves on.

Why a graph, not a gradebook
A list of scores tells you that you failed flip-flops. It can't tell you why. Flip-flops are built on latches, latches on NAND and NOR gates, and those only click once De Morgan's theorems do.
RootCause maps the whole course as a web of topics linked by what comes first, and links you to every topic you've struggled with or mastered. Finding the root cause is a walk back along those links. Every quiz rewrites your links, so the next answer changes too.

Explains, kindly
A short, friendly reason why the root matters, plus notes, an example and the usual trap for every topic.
No wahala. Let's find the real problem.
