Explains in different ways to ensure understanding

We have a sophomore (in MYP on track for the IB curriculum next year) and a senior (currently preparing for IB exams in May). Our senior has been working with David as needed for over a year and our sophomore began working with David several months ago. They both agree that David is an excellent teacher and is able to explain the material in different ways to ensure they understand it. David is very knowledgeable in all math concepts and clearly explains the material. Due to time constraints, occasionally David works with both of students at the same time and is excellent at giving both students the attention needed. I highly recommend David as a math tutor --- he has truly helped both of our students through concepts that were challenging for them.
