“Calcu turns formula learning into a concrete experience. Students understand what they are building instead of simply reproducing a procedure.”
Prof. Marc-André Lavoie · HEC Montréal
“The interface feels familiar, while the learning path is far more guided than a traditional spreadsheet. That is exactly what helps beginners become independent.”
Prof. Sophie Tremblay · Université de Montréal
“Immediate feedback and contextual exercises make practice more useful. Calcu could complement a data analysis or management course very effectively.”
Prof. Daniel Rosenberg · McGill University
“The project connects theory, hands-on work and correction intelligently. This approach can narrow the gap between what students memorize and what they can actually apply.”
Prof. Nadia El Mansouri · McGill University
