I am an experienced mathematics and science specialist. I am here to share with you my knowledge and experience, provide top-quality instruction, and help in the best way possible with whatever ails you! My qualifications include 19 years of experience as a teaching assistant and a substitute instructor at Austin Community College and 16 years of experience as a private tutor. Additionally, I work at El Centro College in Dallas as a mathematics, physics, and chemistry tutor and a chemistry teaching assistant. Furthermore, I graduated with a degree in applied mathematics and a 4.00 G.P.A., earned another in liberal science (also with a 4.00 G.P.A.), and am planning to pursue one more degree in either physics or applied statistics.

Additional background academic information includes:

* Membership in the Phi Theta Kappa National Honor Society (Alpha Delta Pi chapter)and the Who's Who Among Students in American Junior Colleges and Universities honors organization

* Straight A's in all of my mathematics and science courses (engineering calculus, business calculus, differential equations, linear algebra, general statistics, general chemistry, and general physics)

I have the ability to provide students with the most professional instruction possible and communicate classroom material effectively and efficiently. This helps students become creative and independent thinkers and succeed in their courses and careers. I have been frequently complimented on my organizational and communication skills and level of patience in working with students. Through my methodical, step-by-step explanations, detailed examples, and study aids, students comprehend mathematics more effectively. Additionally, my calm and professional demeanor and caring personality instills in students greater peace of mind and a can-do attitude. This leads to greater retention, increased self-esteem, and improved grades. I feel that I can provide students with the best possible instruction and the necessary tools and confidence to help them succeed not only in their math courses but also in other areas of study. Give me a try; allow my experience to work for you. You will be glad you did!

Prior to beginning lessons, if so desired, an in-person meeting may be scheduled for registered WyzAnt students to discuss student-teacher expectations. Moreover, students' parents may sit in on sessions to see how they are conducted, see what my teaching style is like, and gauge their comfort with me as an instructor.

Post-session review guides based on subject matter covered during sessions are also offered. If you would like to have these regularly as a means of either test preparation or additional practice, then please mention so upon lesson's end.

My hourly rate is negotiable; please contact me to discuss possibilities. Furthermore, discounts are given for multiple subjects as follows: $40.00 hourly for two subjects and $35.00 hourly for three or more subjects.

Regarding my cancellation/postponement policy, a minimum of half a day's notice must be given (no charge will be assessed); however, exceptions are made for dire or unforeseen situations (e.g., illnesses and family emergencies). Otherwise, the client's account will be charged according to the following schedule:

Cancellation/postponement 6-12 hours: one half-hour's session time
Cancellation/postponement less than 6 hours: one hour's session time

Special note: I also assist with GED, GRE, ACT, and SAT test preparation but for only the mathematics section of these exams.

Algebra 1

I have tutored Algebra I students over the past two years and achieved a very high success rate. My teaching methodology is: I give detailed written and/or verbal explanations of problems similar to the student's assigned problems before having the student attempt them independently. Moreover, I let the student assume my role by having him/her demonstrate how to solve a problem as if he/she were demonstrating the process to me (making certain to ask many questions as I progress). At the student's request, I provide post-lesson problems called "Do You Remember" exercises to gauge their recollection and comprehension of the lesson material; many of my previous students loved and appreciated them, as it helped them to better retain the material and greatly improve course performance. Algebra I is a moderately difficult course, but my teaching of it makes for easier and greater understanding, less intimidation, and increased student confidence.

Algebra 2

I have tutored Algebra II students over the past five years and achieved a very high passing rate. My teaching methodology is simple: I give detailed written and/or verbal explanations of problems similar to the student's assigned problems before having the student attempt them independently. Furthermore, I let the student assume the tutor's role by having him/her demonstrate how to solve a problem as if he/she were teaching me the process (making certain to ask many questions along the way). Moreover, at the student's request, I provide post-lesson exercises (I call them "Do You Remember" exercises) to test their recollection of the lesson material; many of my previous students loved and appreciated this, as it helped them to better retain the material and greatly improve course performance. Granted Algebra II is a difficult course, how I teach it makes for easier comprehension, less intimidation, and greater student confidence.


I tutor both high school (Pre-AP and Calculus AB; I have not tutored Calculus BC as yet but am confident that I can do so) and college-level calculus (through Calculus III) and have done so for nineteen years. Of all the students who I have taught privately in this subject, all earned passing grades. Moreover, I have experience in preparing students for the AP Calculus examination; I have coached several students to either perfect or near perfect scores on this test. I can also assist with preparation for the CLEP Calculus examination; if you are preparing for this test and would like help in doing so, then please contact me.


I assist primarily with high school chemistry, but I can also help with college-level introductory and general chemistry. Furthermore, I help mostly with the lecture portions of the above courses.

Differential Equations

I have tutored differential equations for many years and still do now and then. Moreover, I have taught in topics from this course in other courses such as Business Calculus I and Business Calculus II. Of all the students I tutored, all earned A's and B's. From these experiences, I feel that I am rather competent in this subject.

Finite Math

I have tutored finite mathematics (i.e., mathematics for business and economics) off-and-on for the past nineteen years. I can handle such topics as linear and quadratic functions, matrices, linear programming, elementary counting methods and probability, and basic statistics (feel free to contact me for further information on the topics I can cover). I tutor these topics in very much the same fashion as I do topics from other mathematics areas. I feel that I am very competent in this subject (most students who I have private-taught in it earned A's and B's) and can provide the best possible assistance.


This past year, I private taught a high school student in Pre-AP Geometry for the first time (this was my first formal exposure to geometry in almost three decades) with good success (the student earned a high B). After having researched the course material the summer prior, accessed many online practice worksheets, and preparing the student for some of the course material in advance, I did not find it terribly difficult; I feel that I am relatively competent in it. If you need assistance with the course or have any questions regarding my prior experience, then please feel free to contact me.

Special note: I assist with Pre-AP Geometry only; I cannot assist with AP Geometry.


I have been tutoring pharmacology since 2004. I have coached numerous pharmacology students and brought them from failing grades to either perfect or near-perfect marks on their dosage calculations examinations. I am not proficient in the theoretical aspect but am well-skilled in the computational aspect. I private-instruct students in pharmacology and am quite comfortable doing so.


I assist primarily with high school physics (at the Pre-AP and AP levels); however, I can help with college-level (algebra-based) physics (the first semester and most of the second semester). Moreover, I can assist with certain areas of the first and second semesters of university-level (calculus-based) physics. Most importantly, I help mostly with the lecture portions of the aforementioned courses.


I tutor precalculus at the high school and college levels and have done so for many years. My teaching methodology for this course is very similar to that for Algebra II, except the level is more sophisticated. The topics covered are similar to those discussed in second-year algebra and trigonometry courses save for additional topics such as sequences, series, and introductory calculus material being covered. My success rate in this course is rather high; I consider it among my best subjects to tutor.


I studied probability in my engineering calculus and statistics courses; moreover, I currently tutor in this area and have done so for many years. (See the "Statistics" section of my profile for a complete description of my qualifications.) Additionally, I have taught students (all of who succeeded) who have taken business statistics at the college and university levels. Via these experiences, I am quite comfortable with this topic and greatly competent in it.


I currently tutor statistics and have done so since 2006. Even before then, I taught a considerable amount of the subject material (not only in this course but also in courses such as Mathematics for Business and Economics and Business Calculus II); moreover, I received training in the MINITAB software that statistics students sometimes use. Of all the statistics students I have taught, all but one earned A's and B's as final grades. From these perspectives, I have considerable experience with the course material. (Special note: I teach statistics topics from such disciplines as business and sociology. However, I do not specialize in engineering statistics.) Furthermore, students request assistance with statistics using computer software now and then. I can do so via MINITAB and (at times) Excel but not SPSS.


I tutor trigonometry and have done so for many years. My teaching methodology for this course is very similar to that for pre-calculus (many of the trigonometry topics covered are also very similar). The only difference is that such topics as sequences, series, and conic sections are not covered. I enjoy teaching this course as much as I do pre-calculus; it is among my favorite tutoring subjects. Moreover, my student success rate in the course is rather high. Most of my students who pay careful attention to my explanations, devote the necessary time, and input the necessary work generally earn at least a "B" grade.

University of Houston (Applied Statistics)

Corey Is A Math Genius As Far As I Am Concerned — I am very impressed with Corey. There is not a statistical operation that he didn't know how to solve. When I was looking for a tutor, I was very desperate to get help. Therefore, it could have been Mickey Mouse because because I did not checked his background. He has not disappointed me thus far. I think the world of Corey! My grades went up from "D"s to a high B's and A. Corey is very patient an ...
