When looking for a math tutoring service online it is important to ask a couple of key questions. Firstly, how much do you want to spend? And secondly, how much help are you requiring.
How Much Do You Want To Spend?
When it comes to price I look at it this way, don't go for the cheapest person because if you go for the cheapest then it is important to leave a bit extra for the risk you run. And if you are going to do that then you may as well pay for someone who can do the job in the first place.
Additionally you will need to look at the service you are getting for your money. Some math online tutors offer software with lessons included, others are one on one lessons. What's the length of the service? Ask if you can have a 15 minute free lesson to try out what it is they do. This can often help you decide if the service will tick all the boxes. Additionally the tutor may offer shorter lessons at a lower price. A tutor is not only helping you with maths they are helping your over all confidence and should teach you skills such as exam and assignment skills. Shop around to find a deal that best caters for your family's needs.
How Much Help Are You Requiring?
Pretty easy really, are you looking for someone to develop tutoring service online your skills over the term or semester? Or, are you looking for a quick overnight study session with a tutor there to help you out?
Most math online tutors will offer both; however the other decision you will need to make is that of the level of tutor contact. By contact I mean 1 on 1, face to face lessons, or will instant messenger suffice?
Some math online tutors conduct lessons via Skype or other video calling technology. The advantage of video calling is that you can speak with your tutor face to face and not have to type your responses. In my opinion it is easier to converse with someone you can see, then having to type in order to get the point across.
Basically you simply need to work out what your needs are. If you require a quick fix than maybe a lesson with an automated tutor will work. But if you are after lasting results then find a reliable tutor who will develop a best fit for your family.
