How do online classes work?

All classes are live and fully online. Lessons use screen-sharing, interactive problem solving, shared materials and lesson recordings or summary notes so progress is easy to follow. At the end of each session, students leave with homework, review priorities and a clear target for the next lesson.

How is the diagnostic assessment done?

We measure your current level via a short intake interview and/or a diagnostic test. Based on the result we propose a study plan and class schedule aligned with your target. The plan also clarifies which topics come first and when the first mock exam should happen.

How do you match students to programs?

Your goal (undergraduate admissions, graduate admissions, language proficiency, etc.), your current level, your exam date and your weekly study capacity all feed into a tailored roadmap. When useful, we combine one-on-one tutoring, group classes, mock exams and question-bank practice into one plan.

One-on-one or group classes — which is right for me?

One-on-one is ideal for students who want fast progress, a personalized plan and full flexibility. Group classes can be a great fit when a fixed schedule and peer momentum help. We decide together based on level and goals.

Do you run mock exams and track performance?

Yes. Mock exams are scheduled within your program and results are analyzed at the question level. We surface weak areas, update the plan and track progress over time.

Do you provide study materials and a question bank?

Yes. Each program ships with materials, problem sets and practice resources. Additional question sets and mock-exam plans are added when the program needs them.

How are instructors selected?

Our instructors are experienced specialists in the relevant exam, with a track record of moving students to their target score. We match by subject, goal, level and program tempo.

Are class times flexible? Are make-up classes available?

One-on-one programs are highly flexible. Cancellation, rescheduling and make-up rules vary by program type; we organize make-up sessions as quickly as possible.

How is pricing determined?

Pricing is set by exam type, format (one-on-one or group), package scope and goal. We're happy to walk you through the right options in a free consultation.

What happens if I'm not satisfied after the first lesson?

Satisfaction matters. If the first lesson didn't meet your expectations we run a quick check (instructor fit, program adjustments, etc.). If you're still not satisfied after the first lesson, we always offer a 100% money-back guarantee.
