Meet our Science Teachers!


Ms. Drust

Biology Instructor

Ms. Drust is a certified Biology teacher with over 15 years of experience teaching AP Biology, Honors Biology, and SAT II Biology. With her extensive experience in high school education, Ms. Drust is familiar with the deficiencies of a typical high school biology class. She uses this knowledge to target her students' weaknesses, helping them to achieve maximum scores. Ms. Drust is especially familiar with the recent changes to the AP Biology exam, and does a phenomenal job in preparing students to perfectly answer free response questions. In addition, she encourages students to apply mathematical concepts to solve real world problem as opposed to rote memorization. Her targeted and effective teaching methods have helped many a student to succeed on AP and SAT II  Biology exams.

Mr. Evans

Chemistry Instructor

Mr. Evans is a certified AP Chemistry teacher who has been teaching AP and Honors Chemistry for over 20 years. He holds a Masters degree in both Chemistry Education and Education Technology. In class, Mr. Evans evaluates his students' strengths and weaknesses and designs lessons to specifically address the areas that need improvement. He thoroughly reviews concepts, introduces problem solving techniques and strategies, and deepens his students' understanding of chemical principles. He has helped countless students to achieve the highest possible scores on standardized chemistry exams, and has maintained a class average of 4.4 on the AP Exam. Last year, his AP Chemistry students at Marlboro Learning Center's South Brunswick location all achieved perfect scores. When it comes to getting a perfect score on the AP and SAT II Chemistry exams, Mr. Evans knows what it takes.


Mr. Kovalcin

Physics Instructor

Mr. Kovalcin is the author of  the textbook Honors Physics, Volumes 1 & 2. He has taught physics for over 36 years at various institutions, including Monmouth County Science and Engineering Center at Manalapan High School, where he has taught lab physics, AP Physics 1 & 2, AP Physics C Mechanics, and AP Physics C Electricity & Magnetism. He is dedicated, well-organized, and thorough. Additionally, in 2008 and 2009, he coached the Manalapan HS Physics team to first place in the National Science League, and four of his students became members of the national US Physics Team. As a former student so eloquently put: "Mr. K. definitely knows the physics material well. He can clearly and accurately explain difficult concepts so that they can be understood. He can also explain the basis and origin of the laws of physics, as well as their applications. Lessons are not spent covering material as fast as possible, but rather aiming for depth in each topic."


Dr. Demaree

Physics Instructor

Dr. Demaree has a PhD in Physics a with concentration on Science Education, and has over 20 years of experience teaching AP/Honors Physics. She served on the test-writing committee for CollegeBoard's AP Physics exam, which requires calculus, and has spent several years grading AP exams for CollegeBoard. She has been a college professor and a high school teacher. The bulk of her career has been studying the most effective practices for teachers to employ in order to have the biggest impact on students. She is passionate about improving student confidence, self-efficacy, and fundamental, transferable skills. She has taught at prestigious institutions, including Georgetown University. Dr. Demaree has helped numerous students to attain a perfect 5 in AP Physics.
