I spent 8 years at Lake Tahoe Community College Learning Center tutoring math from general math to Calculus, this mainly was Algebra I II, Trigonometry, and Pre Calculus. There I helped hundreds of students get good grades in their math class and also helped many high school students prepare for University and Military assessments.

I spent 8 years at Lake Tahoe Community College Learning Center tutoring math from general math to Calculus, this mainly was Algebra I II, Trigonometry, and Pre Calculus. There I helped hundreds of students get good grades in their math class and also helped many high school students prepare for University and Military assessments.
Recently I have been consulting in Tex Typesetting

I am retired from a career in the field of architecture and construction and engineering also worked for the government in the field of surveying and mapping. I am very aware how much Math is critical to many careers and many advancements require math tests even if it appears unrelated.

The subjects I focus in on the most are Math 140 at UH, the IB math (like the one at KHS) and the AP AB-BC Calculus (most recent was the one at Ewa Beach HS), also have been recently helping people prepare to pass the GRE math. These students I saw on a weekly basis.

The High Schools I commonly see are students from are Kamehameha, Kiaser, Miliani, Ewa Beach, and now Waialua and Wahiawa, there are others also.

I have students now that I have seen every week for over 2 years. Even tho now they do well in class and get A's they still see a strong benefit in tutoring. many are in sports etc, and this really helps them keep on top of things and do well academically, I often get referrals from these students. Also, many schools do offer tutoring but students say that can't receive the attention and time they really want. I have seen too many students that were failing and dramatically in a short time move to A and B level, they sure were happy about that.

I usually meet students, at the Barnes and Nobles at AMC, any of the Starbucks, Sure Shot, Surfers Coffee Bar and recently at the Leeward Learning Commons, and UH West in Kapolei. And of course common places in Wahiawa and Haliewa,

In just the short time I have tutored in Hawaii, I am amazed how many students I have seen, by far the very best of it came from Wyzant.

GRE

GRE

The Graduate Record Examinations (GRE) is a standardized test that is an admissions requirement for many graduate schools in the United States. It contains questions from many fields of mathematics. About 50% of the questions are on calculus (including multivariate calculus), 25% on linear algebra, and 25% on a broad variety of other topics typically encountered in undergraduate mathematics, such as abstract algebra, point-set topology, elementary number theory, probability and statistics, as well as real and complex analysis.

Computer

Desktop Publishing

Desktop Publishing

I mainly advise students and teachers on creating special documents such as Peer Reviews, Special PDFs that inform the public on Science and Math. And even just Homework worksheets and Test Reviews. There is a strong consensus now that these should be done in Tex writers like Overleaf or ShareLatex. Since this is written in code first then cloud computed to the eventual image for publication many need to refer to consultants to produce this. All this can be done via online and thru Wyzant.

Elementary Education

Elementary Math

Elementary Math

Of the many elementary students I have tutored in Elementary Math most of the help has been oriented toward dealing with fractions, applications of division and multiplication, and introduction to geometric concepts. I also focus on practical application of work problems.

Homeschool

Algebra 1,

Algebra 1

From the many students I have tutored in Algebra 1 this subject is basically an introduction to the variable and plotting. There is also an introduction to the number system past just integers. We are now solving equations too by simplifying terms and reducing them to the value of the variable. We also look at factoring, distribution, and exponents and roots. Plus all this is made practicable by word problems.
Algebra 2,

Algebra 2

Algebra 2 extends algebraic skills and knowledge by exploring the real number system in greater depth, providing exposure to various algebraic, techniques and developing the concept of functions, including graphing techniques and inverse functions. Algebra 2 also includes the study of quadratic relations and systems, polynomial equations, exponents, logarithms, sequences & series, matrices, determinants, probability, & statistics.
Calculus,

Calculus

AP Calculus, 205, 214, military online are my main focus on tutoring. The common experience is seeing the student on a weekly basis throughout the full course frequently resulting in a grade of A or close to it. Provided you are initially set up with Wyzant, I commonly do the first 2 lessons as a courtesy so you can get a take on the sessions. Most see the benefit enough to want to continue. Also I have no transportation cost so my rate is in keeping. I will meet with any student on the Island provided we can work out a place to meet that is convenient. The most frequent have been the Starbucks, Ala Moana Center, UH West and Surf the Nations. The commonly Internet tools referred to are: www.desmos.com This is very useful studying slopes, domains, derivatives. Integrals for area and volume plus many templates such Riemon sums. You can store a entire home work series using the folder feature. www.wolframalpha.com This is a very popular site from Europe. Very valuable for any level of math. It's user interface can be daunting at times but gives a superior graph with an abundance of extra information. The Pro version gives steps but it is too overdone. www.emathhelp.net/calculators/calculus-1/linear-approximation-calculator This us very helpful in checking linear aproximations www.derivative-calculator.net www.integral-calculator.com These are sister sites of various calculators. Just keep in mind that with integrals alternative answers are are common. So the answer given though correct may be different than the textbook answer. TI-nspire CX CAS calculator If you own this. You are aware of its many great features. I would strongly recommend using document mode then you put complicated problems in one small area and make easy adjustments which cannot be done on the calculate screen. Plus with the file folder I have stored nearly every homework problem from the 205 calculus class. of which will be very easy access for the next student I study with. With this I became very familiar with homework and handouts given to students. And now have many pdf's of worked problems that are linked to Dropbox So far have seen calculus students from KCC, HCC, LCC Sacred Hearts, Kaiser HS Eva Beach HS, and Mililani HS. If you taking any of the classes or an online proxy it would be my priority to see you do well.

SSAT

SSAT

The Secondary School Admission Test, or SSAT, is an admissions test administered by the Secondary School Admission Test Board (SSATB) to students in grades 5-11 to help determine placement into independent or private junior high and high schools. There are two levels of the test: the Lower level for students in grades 5-7 and the Upper level, designed for students in grades 8-11. The SSAT consists of two parts: a brief essay and multiple choice sections that include Mathematics, Reading Comprehension, and Verbal. The test, written in English, is primarily administered in the United States and Canada at various test centers, which usually are independent schools. There are also test centers worldwide. Despite the similarity in name, the SSAT is not related to the SAT Reasoning Test and is not administered by the College Board.

Very Patient GRE Math Prep

Preparing to take my GRE made me realize how rusty my math skills really are. I am 3 sessions in with Ray as my tutor in math, and I can already see an increase in my confidence while solving math problems. I appreciate his patience in reviewing the math problems step by step, and can also attest to his way tailoring the lesson to fit the student. Ray has a very pleasant demeanor, never gives up on you, and is a joy to work beside. Never before have I smiled while completing math problems, but with Ray's assistance and guidance GRE math is now FUN. Thank you Ray for the selfless service you provide to the community at very reasonable prices.

Titisha, 7 lessons with Ray

Thanks Ray

I'm currently in Pre-Calculus and Ray help me learn some formulas to help me out with my problems. We also went over a take home quiz. He is current on his knowledge and showed me apps that would help me also. Will definitely use again thanks.
