E

Engagement work program
The document linking engagement objectives to the specific procedures that will achieve them, guiding fieldwork and enabling supervision.
Evidence sufficiency
The quantity dimension of audit evidence: enough factual, adequate, and convincing information that a prudent, informed person would reach the same conclusions as the auditor. Companion criteria are relevance and reliability.
Exit conference
The closing communication at the end of fieldwork where the audit team and management review results, confirm factual accuracy, and discuss action plans before the final engagement communication is issued.

R

Root cause
The underlying reason a difference exists between evaluation criteria and the observed condition. Action plans that address symptoms rather than root causes leave findings likely to recur.

W

Workpapers
The documentation of engagement procedures, evidence, and conclusions. Adequate workpapers let a skilled internal auditor who was not involved in the engagement understand and retrace the work.

About FreeFellow

Jeffrey Ting, founder of FreeFellow
Jeffrey Ting
FSA, CFA · Founder

FreeFellow was built by Jeffrey Ting, a credentialed actuary and CFA charterholder who passed thirteen of the hardest exams in finance on the first attempt, and paid four-figure prep fees for every one. The learning itself was always free. The price was a moat.

So he started writing his own questions, then lessons, then mock exams, until it grew into a full prep platform covering 40 finance credentials with more than 44,000 original practice questions. The name says exactly what it is: the question bank is free, and Fellow is what you become once you pass.

01
Cost shouldn't decide who gets in.

The exam is a fair gate. A four-figure prep course is not. FreeFellow takes the second gate down, so the exam is the only one left.

02
Free should mean free.

No trial clock, no email gate, no credit card. The question bank, worked solutions, lessons, and readiness score stay free, and they are enough to pass.

03
Built by someone who sat where you sit.

He paid for the big-name courses, found nothing he respected, and built the prep he wished had existed. Not a marketing team that has never sat an exam.
