I get every killer problem right, so why do I keep slipping on basic calculations..?
I can't figure out where I went wrong, no matter how hard I look..
Top tier, but slips a lot
100 in practice, 60 on the real test?
I focus on accuracy and the time is already gone..?!
I'm so weak when it counts..
They look alike but every problem is different..?!
Ugh.. another applied problem..! Other students seem to solve them so easily..
How can I fully understand this kind of problem and solve it fast?
Why your child's math grades
aren't going up
Mindless drill repetition
Studying by simply repeating tons of problems
has its limits in finding and fixing
the underlying weaknesses.
Pouring water into a bottomless bucket
Pushing ahead in the curriculum without solid fundamentals
ultimately leads back to square one — an inefficient
cycle of learning.

without solid fundamentals leaves you

Group lessons can't get personal
Group lessons with many students
make it hard to gauge each student's understanding
and provide tailored feedback.

Memorizing solutions, not concepts
Memorizing only solutions and explanations without understanding the concepts
leaves you defenseless when you face problems
that require applying the concepts.

Why CARI's AI math solution
is different.
A wide range of personalized learning features
Diverse learning content
Use the variety of features prepared by difficulty
in a structured way that fits your learning state.
Solution-process feedback system
Provides feedback based on your own work, not just generic explanations,
filling the learning gaps you might miss while solving so you can study deeper.
Manual Solution
Identifies errors in your work and gives feedback
It tells you which part of your work is wrong and how to approach the problem,
and offers a sub-unit course on the topic you missed for deeper learning.

and how to build a strategy from that interpretation, with AI.
Step 1
Read the problem closely
Read the problem slowly and
look for clues to the solution.
Step 2
Build a strategy
With AI Perry,
build the strategy to solve it.
Step 3
Concept study
Watch videos for the formulas
and concepts you need.
