Course intro

How a Grade 8 group class actually runs

Parents usually want three answers: how many kids share the slot, whether every child still speaks, and how you will know it is working.

  • Warm-up so the whole batch revisits last week’s weak spot
  • New teaching with visuals, then shared guided practice
  • Every student answers at least once each class
  • Weekly parent note: topics, accuracy, home practice

NRI families in the United States

Grade 8 math coaching for US schools, with Indian faculty for NRI students

We coach small-group live classes for Grade 8 students across the United States on US school and Common Core pacing. We also specifically support NRI and Indian-origin families living in the US.

Built for US Grade 8 classrooms

Lessons follow your child’s US school topics, homework, and state-style practice. English instruction stays the default so school language and coaching language match.

Indian faculty who teach US math

TestPrepKart is based in India and works with Indian faculty who teach US Grade 8 math online. Many NRI students find the first principles easier to grasp when the tutor can explain patiently in a familiar teaching style, while still staying locked to the US curriculum.

Why NRI parents in the US choose this

You get US-aligned Grade 8 coaching plus tutors who understand how Indian-origin learners often build number sense. That mix helps when a child is strong in drills but needs clearer word-problem language for US school tests.

What is included

Everything in the Grade 8 group plan

Core coaching for the year. If your child later needs a private topic pack, that is a separate option.

FAQ

Questions parents ask before they book Grade 8 group

How much does the Grade 8 group math class cost in the US?

From $18 USD per class on a 12-month plan, about $1872 per year at two classes a week. Your counselor confirms open seats in the free demo.

How many students are in a Grade 8 group?

3 to 5 students in the same Grade 8 band. Batches stay small so every child still answers aloud and gets homework notes.

Is the group course aligned to US Common Core?

Yes. The year plan follows the Grade 8 hub syllabus and quarters: Jun-Sep irrationals through linear systems, Oct-Nov functions, Dec-Feb geometry and Pythagorean work, Mar-May bivariate data and Algebra 1 readiness.

How is a group class different from 1:1?

Same Grade 8 curriculum and English instruction. You share the slot with a few peers, so the per-class price is lower. Private 1:1 is still available if you want a dedicated tutor.

Can we join mid-year?

Yes, when a seat opens. After the demo we place your child in the best-fit batch and rebuild the remaining months around school pacing.

What language are classes taught in?

English, for US school students.

Do you coach NRI students in the United States for Grade 8 math?

Yes. We coach Grade 8 math for US school students nationwide, and we specifically support NRI and Indian-origin families in the United States. Our Indian faculty teach US curriculum topics in English, which helps many NRI students understand basic principles more clearly while staying aligned to Common Core and school pacing.
