What our practice questions measure.

Built around the exam

• SAT: 54 Reading and Writing questions in two 32-minute modules, plus 44 Math questions in two 35-minute modules. Short passages, evidence and synthesis tasks, four-choice answers and numerical entry. The Math set contains 11 numerical-entry questions.
• GRE: 27 Verbal and 27 Quant questions in 12- and 15-question sections. Text Completion has separate choices for each blank; Sentence Equivalence has six choices and requires two selections. Quant includes comparisons, five-choice problems, select-all and numerical entry. A separate 30-minute original Issue task includes a self-review checklist.
• GMAT: 21 Quant, 23 Verbal and 20 Data Insights questions, with 45 minutes per section. Data Insights includes data sufficiency, tables, charts, multiple sources and two-part analysis. Tables can be sorted; source tabs and response parts are interactive.

Difficulty means reasoning demand

An easier question usually requires a direct interpretation or familiar procedure. A medium question combines steps, distinguishes related claims, or requires an appropriate model. A harder question adds interacting constraints, abstract parameters, a subtle inference or plausible competing explanations. Longer arithmetic alone is not a reason to call an item hard.

These are editorial estimates. We have not calibrated item difficulty against a representative student sample or linked it to official scores. An easy/medium/hard label is shown in the final review, not as a clue during a timed attempt.

How to use each mode

Timed sections: section clocks follow the standard published times. Earlier sections lock when completed. GMAT requires an answer before moving forward and offers a section review with up to three saved answer edits. You can choose the GMAT section order.

Untimed study: move freely among questions and take time to work through the reasoning. Finish when ready to see explanations.

Multiple-selection and multi-part questions receive credit only when the complete response is correct. A partially answered item is attempted but incorrect; a wholly blank item is unattempted. No scaled SAT, GRE or GMAT score is generated.

What remains different from the official test

The question sets and second sections are fixed; there is no adaptive routing or item-response scoring. The interface, calculator availability and transition screens differ from the official applications. Bring an appropriate calculator where the section permits it. GRE sentence-selection practice uses numbered sentence choices. The writing exercise is separate and has no automatic grade.

These resources are independently authored. They are not official exam questions or endorsed by College Board, ETS or GMAC. Passages and datasets are original or hypothetical teaching material; no student score gains or real research results should be inferred from them.

Answer review

Each question includes a stable item ID, a keyed answer and an explanation. Numerical results and assumptions are checked; response-format and scoring tests check numerical equivalence, all-or-nothing multi-part credit, incomplete responses and answer counts. A second review looks for ambiguity and weak distractors. This is editorial and software validation, not independent human tutor certification.

If you spot an ambiguity, include the item ID and your reasoning when you contact us. We can review the exact item rather than guess which version you saw.
