Your child's situationNot sure where to start
- The class that fits
- We look at the diagnostic results alongside your child's school curriculum to set their starting level and textbooks.

Here's what to know before you enroll: consultation and the diagnostic assessment, enrollment and payment, and what your child needs for online classes.
Check what to prepare, then request a consultation.
What happens: We ask about your child's grade, school curriculum, and goals, then pick the subjects they need right now. We won't push you to sign up for several subjects at once.
What happens: A diagnostic assessment in each subject shows where your child is in the material and how well they know it. A learning profile assessment shows how they study.
What happens: From the results, we choose what your child will learn and which textbooks to use, then assign an instructor who majored in the subject.
What happens: You choose how many classes a week, enroll for the month, and your child has their first class.
What happens: Assessment results decide what to review next month and what to learn next. You also decide each month whether to continue.
Assessments happen every class, at the end of each month, and every quarter. See how you receive results and instructor comments

LAB.CO teaches mostly online, with in-person classes at our Seocho center in Seoul. You can choose either one based on where you live, your schedule, and your child's learning goals. In consultation, we'll go over whether in-person classes are possible for your child, and when they run.
In an enrollment consultation, we ask about your child's grade and what they're learning now, then decide with you which subjects to assess, the class format, and class times.
