Outstanding Tutor!

On my first calculus exam, before finding Graciele, I scored a 56%. On my last calculus exam, after many sessions with Gra, I scored a 101%. Gra helped me achieve a feat that would have been impossible alone: an A in calculus. Gra makes even the most difficult material surmountable; she truly wants you to understand and succeed. Not only is she an amazing tutor, she is a kind-hearted and accommodating person. I highly recommend her to any student looking to excel in a math course that is troubling them!

Samantha, 8 lessons with Graciele

Knowledgeable and patient and meets the student where they’re at.

My daughter needed A LOT of guidance in preparation for taking the ACT again. Graciele was able to identify where my daughter struggled and has been working with her for countless sessions to help her understand and grasp some key concepts.

Excellent tutor!

Graciela has really helped my son who is taking an online summer Precalculus course that is somewhat difficult to follow. Their sessions are very interactive, keeping him engaged and motivated. My son took it upon himself to book Graciele for additional sessions..the ultimate proof of how effective she is!
