Alejandro - Know your tutor
Hi! I’m Alejandro — a passionate Math tutor with over 10 years of experience helping students from elementary school through college develop confidence and mastery in mathematics. I hold both a Bachelor’s and a Master’s degree in Chemical Engineering from the New Jersey Institute of Technology (NJIT) and currently work as a Senior Quality Engineer. My strong analytical background allows me to make even the most challenging math topics — from basic arithmetic and fractions to algebra, geometry, calculus, and statistics — clear and engaging. I take pride in breaking down difficult problems into simple, logical steps and creating personalized lesson plans that match each student’s learning style. Over the years, I’ve helped hundreds of students raise their grades, prepare for exams, and build lasting confidence in math. Whether your goal is to strengthen the fundamentals or tackle advanced topics, I’ll guide you every step of the way with patience, clarity, and real-world examples that make math make sense.

Class overview
My teaching approach is built on clarity, structure, and adaptability. I start every lesson by assessing the student’s current understanding and identifying any knowledge gaps. From there, I design a personalized learning plan that breaks each concept into clear, manageable steps. I combine theory with real-world examples so students see how math, chemistry, and physics connect to everyday life and engineering applications. During sessions, I encourage students to think aloud, explain their reasoning, and solve problems independently — building both confidence and critical-thinking skills. I also use warm-up questions, guided practice, and review checkpoints to reinforce mastery before moving to the next topic. For younger learners, I incorporate visuals and interactive exercises to make math engaging and fun. My ultimate goal is not just to help students improve their grades, but to help them truly understand the “why” behind each concept so they can apply it confidently on their own.
