Your review of last night's mock

What cost you the mostQuestion 3 in Verbal. You stayed too long, then rushed the end and lost five in a row.

The habit behind itOn Data Sufficiency, when you are unsure, you reach for “both together”.

Ask your tutor

Why is my Data Sufficiency so bad?

When you are unsure, you reach for “both together”. It has cost you 12 questions, and on most of them one statement was already enough.

Today: ten questions where you test each statement alone first. About 10 minutes.

Take a mock

A full mock with the real test's timing, or a practice test you already took.

See every mistake

Your tutor explains each one on the question itself, and shows you which ones keep coming back.

Do today's task

Your tutor plans the next step. You open it and do it. No deciding what to study.

Explains the miss

On your question, in the order you should have reasoned.

Is x > 2? (1) x² > 4 (2) x³ > 8(1) allows x = −3, so it is not enough alone.(2) gives x > 2 directly. The answer is B, not C.
