You can find some really good resources for math test prep in the used bookstores in a college town. Some examples that I like are: (1) Humongous Book of ______________ Problems (fill in the blank with your math topic); (2) the REA Problem Solvers series; and (3) the Schaum's Outlines. If you don't live near a college town it might be worth a Saturday trip just to buy books. Alternately, all of these are available (used) through the Amazon Marketplace sellers at really low prices. You should preview each title of these book series that you might be considering to be sure you like the authors style. Each one is different. You may like one series' treatment of Pre-Calc but prefer a different series for Calculus. So how do you use these books ? They are an alternate resource for explanations of basic concepts and problem solving techniques. You should use them as 'hint mills' and sources of problems to make up your own practice exams. Sometimes you will... read more
What's happening in the world of private tutoring?

A current poll by Wyzant of tutors indicates a large majority of tutors assign homework to their tutees. Seriously? My students all have plenty of teacher-assigned homework they are required to do. They can use this homework to practice what we've done in tutoring sessions. More homework? Not if you want to keep the student!
I have studied Electrical and Computer Engineering and received Master degree in 2008. While I was studying at university, I worked as a teacher assistant. I have taught many courses to undergraduate and graduate students. In addition, I taught a lot of elementary and high school students as tutor. Both of these experiences convinced me to pursue tutoring as a career. Therefore, I have tried hard to become a good teacher. I realized that teacher preparation is the major determinant of a great teacher. I have taught large variety of courses; however, my best experience is computer programming. Right now, I have some college and high school students whom I am teaching Java, C/C++, Matlab, and object oriented programming. I love teaching the computer programming to any student and can transmit information in the best way at minimum time. If you have any problems in programming and want to become ready for your class or doing your homework, I could help you. You are going to... read more
I have a web cam and I use it with Skype to see distant friends and family that I am talking to. It is nice to 'see' people even though they are in another state or even another country. Very helpful when you move away from 'home' and still want to feel close by.
Direct Current (DC) Power is becoming more prevalent in providing power to residential, commercial, and industrial systems. Solar Photovoltaic (PV) Systems and some Wind Turbine Systems implements DC power. Some Wind Turbines implements the use of Alternating (AC) generators However, some Wind Turbines implements DC generators. These turbines requires the use of an Invertor. The Invertor converts DC to AC Power for use in an AC power system. Solar PV Systems also consist of an invertor to convert DC Power to AC power. However, the by using an invertor power is loss in the conversion from DC to AC. Therefore, this power loss is eliminated if DC power is used directly. More and more innovation ways are being developed that directly uses the DC power that is generated from Solar PV and Wind Turbines. HVAC systems implementing DDC controls can implement the DC power for its controls. Furthermore, with many electronic products (i.e TVs, computers, mobile phone chargers,... read more
Gentle student, If you're anything like me, at times you've wished for an easy way to work math problems and get the answer in the back of the book.Of course, you probably tried just copying the book's answers on to your homework paper only to have that "unreasonable" teacher of yours refuse to give you credit for all those answers!... something about not showing enough work. Well, you're in luck! I've taken a couple of math concepts from the internet,combined and refined them into a technique will take answer you have, no matter how wrong or bogus, and "transmogrify" it into the answer in the back using simple algebra which you can use to show full work. I call this technique The Correct Answer Algorithm (it's so simple it needs a really complicated name to make it sound sophisticated enough to impress your teacher.) So here it is... the algorithm which will in short order transmogrify your answer into the answer in the back of the book: X = Ff · Xu... read more
I don't really like the term "engineering ethics", because it implies that right and wrong may only be defined within the scope of a discipline, but as it is the term du jour, oh well. As an undergraduate, you get a few courses here and there that touch on "engineering ethics", or maybe a special class devoted to it, and most all the kids I knew kind of blew it off. It was an easy class, you just BS a paper or two about a famous disaster, and how the engineers were to blame, and you get an A. Then you graduate, go out into the workforce, and start playing the CYA game. You may not like to hear it, but that's a pervasive theme in modern business. You don't ask "How can I make this situation right?" You ask "Who is on the hook for this, and how can I make it NOT ME?" That's not honesty. That's not engineering. Insofar as you deal with hard facts, careful estimates, and the reality of universal physical laws, you're on the hook to DO IT RIGHT. It can be done, that's... read more
