A tutor will generally not fully measure their pupil's pace properly and can push too much information or too little information on them, which either way is a lose/lose scenario. The only way for a person to really learn is to do so at their own speed in order to maximize the knowledge load. Not only this, but a tutor profits per session, per hour, or per week.
Now with THAT in mind... A tutor teaches your child multiple words for an impressive vocabulary, but not how to properly use them in any given situation, or even worse... the tutor teaches their student in 3 weeks what could have taken 3 days. Why? Because they want to make the process as long and drawn out as possible, but at the same time show results.
Indeed, you will see results if they are going over the same thing 3 weeks straight, but THINK for just one minute how greater of a profit they are making by prolonging the process. For example, take look at the medical field. Why would they cure flu when they can just suppress it and make it go away gradually, thus making it possible for them to sell you more medicine. It's the same scenario. Tutoring is a business, and must be treated as so.
Now, that you understand this. I personally have learned a massive amount of languages, all on my own, generally being able to speak them fluently in just above 3 months time frame. Now that being said... I have NEVER ever hired a tutor... but instead have discovered and made use of a couple products. Now before you think this is a sales letter, think about anything you have. How would you know about it if someone didn't recommend it to you? You want what really works, right? Okay then.
Second... "I" am not connected in any way to this product whatsoever, and am only letting you know about it because of the thought of innocent children wasting time thinking they are learning when in actuality they as well as you are being scammed. Don't be a fool. seriously... instead, go pickup a FREE, yes free, 6-day course at http://squidoo.com/LearnAnotherLanguage/ and then judge for yourself the product's worth. If ya'll don't see a BIG difference in those 6 days, then by all means forget you've ever read this, but if you DO... then at least you'll know you have the option of purchasing a product you will actually achieve results from as opposed to wasting your hard earned cash.
