How a focused session works
01Bring the evidence
Missed questions, score data, or a specific concern.
02Work it live
See the pattern, correct the habit, and practice the fix.
03Leave with direction
Know exactly what to do before the next session.
Targeted by design
Stop reviewing everything.
Stop reviewing everything.
Fix what is costing points.
Private tutoring is most useful after practice reveals a pattern. We use the student’s actual work to find where a tutor’s explanation can make the biggest difference.
- Start with missed questions and real performance
- Separate content gaps from pacing and test-taking habits
- Prioritize the skills that can change the score fastest

A human sees the pattern
The wrong answer is rarely the whole story.
A tutor can see whether the real issue is interpretation, process, timing, or confidence—and correct it while the student is working.
- Ask questions in real time instead of guessing at an explanation
- Watch a tutor work through the question step by step
- Practice the new approach until the student can use it independently

READING · SUPPORTING EVIDENCE
Which answer is supported by the passage—not just mentioned?
A
Restates a detail from the opening paragraph.
B
Connects the claim to the author’s evidence.
C
Introduces an idea the passage never proves.
TUTOR NOTE
“Mentioned” is not the same as “supported.”
Underline the claim first. Then require every word of the answer to earn its place.
Pattern identified
