Common Questions
Frequently Asked Questions.
How much do programs cost?
Pricing is customized after your free diagnostic consultation based on program type, session frequency, and timeline. We don’t offer one-size-fits-all packages. Contact us and Olivia will walk you through options that fit your student’s needs and budget.
How long does the SAT Intensive program take?
Most students complete the full SAT Intensive in 3β4 months with weekly sessions. Some students with more time before their test date extend to 5β6 months for deeper mastery. The timeline is always built around your target test date.
Do you offer online sessions?
Yes β fully online sessions are available and use the same curriculum, materials, and instruction as in-person sessions. We serve students across the SGV and beyond through online format. Bluebook practice tests work seamlessly online.
How quickly will my student see improvement?
Most students see measurable improvement within 4β6 weeks of starting the Logic-First Framework. Students who complete the full program average 200+ point improvements. Results depend on consistency, effort, and starting baseline.
What makes Gangnam Prep different from large test prep chains?
Three things: methodology, specialization, and individual attention. Our Logic-First Framework is proprietary β not licensed from a national chain. Olivia teaches every session herself β not a rotating roster of tutors. And our curriculum is built specifically for the Digital SAT, not adapted from paper-era materials.
Can you teach in Korean?
Yes. Olivia Bang is fully fluent in Korean and can conduct sessions in Korean or English based on what’s most comfortable for the student. Many of our Diamond Bar and Walnut families prefer Korean-language instruction.
