Questions

Geometry FAQ

What is Geometry?

Geometry is the standard US course on shapes, proof and measurement, usually taken in Grade 9 or 10. It covers congruence and similarity, right triangles and trigonometry, circles, coordinate geometry, area and volume.

What do I need before taking Geometry?

Algebra 1 is the usual prerequisite: solving equations, graphing lines and working with radicals.

Are the online Geometry classes one-to-one, or do I have to join a group?

Classes are live and one-to-one with Janvi Mam, Ph.D., on Zoom or Google Meet, so you never have to join a group or share the class with other students. If you prefer to study with a friend, small-group sessions of 2-3 students in the same course are available at a reduced per-student rate.

What are the benefits of one-to-one Geometry tutoring?

The lesson follows your own pace and gaps instead of a class average. Every minute goes to your questions, so you can ask anything without worrying about others. Weak topics are spotted and fixed quickly, and the plan can be matched to your school tests and exams.

Can classes fit my time zone?

Yes. Timings are arranged for students in Eastern, Central, Mountain and Pacific time, so you can ask for a slot that works after school or at the weekend.

Can I try a class before I commit?

Yes. You can book a free demo class, meet the teacher and see how the class runs before deciding.
