Choosing an online GRE tutor: test the quality of an explanation
A useful GRE explanation should show why the keyed answer fits and why the alternatives fail. An impressive vocabulary or a confident claim about what a “high scorer” thinks is not enough. During a trial lesson, ask the tutor to make the evidence visible.
Check a complete question, not a missing context
A sentence such as “The findings forced researchers to reconsider their assumptions” does not uniquely establish whether those findings were significant, controversial or heretical. Without a more precise context and a complete set of choices, declaring one of those words the only correct answer teaches an unsupported distinction.
Here is an original teaching example with a clearer constraint:
Unlike the earlier explanation, which hid its reasoning behind unexplained terms, the revised account was ______: it defined each term and showed every step.
- opaque
- transparent
- irrelevant
- incomplete
- contradictory
Answer: B, transparent. The description after the colon specifies clarity and openness about the reasoning. “Opaque” repeats the earlier problem. The passage does not support irrelevance, missing steps or a contradiction.
Look for a transferable lesson
The tutor should ask you to identify the contrast and explain the defining evidence, then check the method on a different sentence. Vocabulary still matters: if you do not know an option’s meaning, record that separately from a logic error.
ETS’s Verbal overview distinguishes Reading Comprehension, Text Completion and Sentence Equivalence. A tutor should choose practice from the actual format and your attempted work, rather than treating every Verbal mistake as the same problem.
Confirm the support and terms
Ask who teaches the lesson, what homework feedback includes, how progress will be checked on fresh questions and what the full cost is. You may need focused support for one skill rather than a large package. See GRE tutoring for the service, and bring an original attempt to the first discussion.
