pbmate
Online mathematics platform for grades 5–12, featuring daily problems, step-by-step solutions, and progress tracking for students and parents.

This learning platform is built for students from 5th grade through the Baccalaureate exam who want consistent mathematics practice instead of relying on scattered worksheets or occasional tests. Students receive three new problems every day, with difficulty adapting to their answers, along with complete step-by-step solutions that explain how to reach the result.
It combines daily practice with structured exam preparation, covering middle school, the National Assessment, and the M1 Baccalaureate track. Official exam papers are fully solved, with scores calculated using the same approach as the actual exam. A large archive of more than 9,500 problems also gives students additional material organized by difficulty.
Key Features
Daily Adaptive Problems
Students receive three new problems every day, with difficulty adjusted according to their answers.
Daily sets can be revisited through the problem archive, giving students a consistent practice routine while allowing them to review previous work.
The adaptive approach helps keep practice aligned with the student's current level rather than providing the same difficulty to everyone.
Step-by-Step Solutions
Every problem comes with a complete explanation rather than just a final answer.
Step-by-step solutions help students:
- Understand the method
- Identify where they made mistakes
- Follow the reasoning behind the answer
- Review difficult concepts independently
This makes immediate feedback part of the daily practice process.
Exam Preparation
The platform supports preparation for key school and national assessments.
Coverage includes:
- Middle school mathematics
- National Assessment
- M1 Baccalaureate
- Official exam papers
Official papers are solved in full, with scores calculated as they would be in the actual examination.
9,500+ Problem Archive
Students have access to a large archive containing more than 9,500 problems.
Problems are organized by difficulty level, making it easier to find additional exercises when students want more practice beyond their daily set.
Progress Tracking
Track learning activity and progress over time rather than relying only on individual test results.
Progress features include:
- Practice history
- Chapter-level estimates
- Pace alerts
Students and families can use this information to identify whether practice is progressing consistently and where additional attention may be needed.
Parent Account
Parents can use a separate account to follow a student's activity without relying on the student's own dashboard.
Weekly reports show:
- Active days
- Current chapter
This provides families with a straightforward view of ongoing practice.
No Pressure for Missed Days
Missing a day does not reset the learning process or create additional pressure.
Students can simply continue where they left off, making the platform suitable for maintaining a sustainable practice habit rather than enforcing an uninterrupted streak.
Built For Students and Families
5th Grade Students
Build a consistent mathematics practice routine with daily problems and immediate explanations.
Middle School Students
Use adaptive exercises and chapter-level progress tracking to strengthen regular coursework.
National Assessment Preparation
Practice with relevant material and review fully solved official papers.
Baccalaureate Students
Prepare for the M1 Baccalaureate track with structured practice and exam-style scoring.

Common Use Cases
Daily Mathematics Practice
Complete three new problems each day and use the explanations to understand mistakes immediately.
Targeted Revision
Use the archive of more than 9,500 problems to find additional exercises by difficulty.
Exam Preparation
Work through official National Assessment and Baccalaureate papers with complete solutions and exam-style scoring.
Identify Learning Gaps
Use chapter-level estimates and practice history to see where additional work may be useful.
Maintain Consistent Practice
Continue from where you stopped after missed days without losing progress or being penalized for breaking a daily streak.
Adaptive Practice With Immediate Feedback
The platform combines three parts of the learning cycle:
Practice → Solution → Progress
Students receive problems suited to their current level, can immediately review the complete reasoning, and build a history of their activity over time.
This makes the experience more structured than working through disconnected worksheets, while the large problem archive provides additional material when students need more repetition.
Pricing
The listed subscription price is under 20 RON per week.
The subscription can be canceled at any time, making it suitable for students and families who want ongoing practice without a long-term commitment.
Why It Matters
Consistent practice can be difficult when students rely on occasional tests, worksheets, and disconnected exercise sources. This platform puts daily problems, detailed solutions, exam papers, progress tracking, and additional exercises into one place.
For students, the main benefit is having a predictable daily practice routine with immediate feedback. For parents, weekly activity reports provide a simple way to see whether the student is practicing and which chapter they are currently working on.
Build a Consistent Mathematics Practice Routine
Give students three adaptive problems every day, complete step-by-step solutions, more than 9,500 archived exercises, and structured preparation for the National Assessment and Baccalaureate exams. With progress tracking, parent reports, and a flexible approach to missed days, the platform provides a consistent way to practice mathematics from 5th grade through Baccalaureate preparation.
