What this means for your child
Practice is the method
Thousands of problems, day after day. It is the same habit SparklMind asks of a student: work it yourself, and learn from the wrong step.
Good material should be shared
The guide above is free and open to anyone. The first SparklMind class is free too, with a written plan whether you join or not.
Hard topics can be taught plainly
Teaching IIT-JEE mathematics means taking difficult problems and making each step clear, one student at a time.
Before you trust us with your child
SparklMind is new, and this is what you can hold it to.
What we promise
- Every teacher sits a paper, teaches a watched demo class and passes an identity check
- Every class is recorded, and a parent can sit in on any class
- A written report to parents every 2 weeks
- Not happy after the first 2 paid classes? The month is refunded
What we will not do
