Adam’s story · Private instruction with Woody

From struggling in calculus to a civil engineering degree.

Adam began working privately with Woody while earning Calculus I exam scores in the 40s and 50s. He went on to graduate from Stony Brook University with a 3.6 GPA in civil engineering and later passed the Fundamentals of Engineering exam.

  • 3.6 GPAAt graduation
  • Civil engineeringStony Brook graduate
  • FE exam passedAfter graduation

He describes how practicing and rewriting solutions helped him become more independent—and how he carried those habits into later courses and engineering exam preparation.

Adam put in the work. This is his experience with Woody’s private instruction.

The Woody Calculus method

Turn a worked example into a method you can use.

Pattern first → setup second → computation third.

Recognize the pattern

Identify the problem type and what you need to find or prove.

Choose the method

Match the problem to the right technique, definition, or theorem.

Build the setup

Write the structure clearly before doing the computation.

Train the process

Rewrite each correct solution 3–5 times while saying every step aloud with confidence.

Repeat before bed and the next morning. Then work the problem independently.

Put the Lab to work

Bring the work you’re doing now.
