About Sandra
Learning feels best when the hardest problems become the most rewarding ones to solve. My lessons are intentionally dense but remain accessible for students at all levels.
We spend time on exam preparation and foundational theory before transitioning to application. Each session includes a homework module assigned with every lesson to reinforce the material.
You receive the benefit of my 4 years of fintech experience in every calculation we perform. We focus on the most efficient path to solve for your specific target. This preparation creates a clear map for your academic success.

Mathematics is not just about memorizing formulas; it is often about forgetting the rigid rules you learned in school. I hold a Master of Science in Data Science from Columbia and maintain a career in fintech. My experience spans 4 years of helping 161 students navigate everything from basic homework help to intense competition math prep.
I serve professionals needing calculus or trigonometry for their projects, alongside students aiming for top entrance exam scores. Many people find mental math intimidating until they see it through a practical lens.
I simplify complex quantitative concepts into manageable steps. I enjoy watching students move past their hurdles to tackle higher level material. You will find my approach structured and industry-focused.
