Math, taught one step at a time.

NEXUS Math Tutorials is an online UPCAT Math review. Every lesson is free and open to everyone, the practice sets and mock exams show you exactly where a mistake came from, and our live classes walk a whole batch through the exam together.

NEXUS Math Tutorials was founded and is run by Yobhel Nucum. Before NEXUS, Yobhel taught math one-on-one as Math Tutor Yobhel, and NEXUS grew out of that work: the same way of explaining a problem, every step written out, put online so that any student can learn from it.

Entrance exams reward students who can afford the most review. We want the lessons to be the part that costs nothing, so every UPCAT lesson, and the whole Grade 7-12 Math Review behind it, is free.

How we teach

  1. Free to learnAll 176 UPCAT lessons and the 148 Grade 7-12 lessons behind them are open to everyone, with no account and no payment.
  2. Every step written outNo skipped algebra and no "it is easy to see". Each slide shows one move, and every formula says what its letters mean.
  3. Mistakes point somewhereMiss a question and it links you back to the exact step that teaches it, so you fix the gap instead of guessing again.
