At your speed, you don't really need to learn it unless you have plans to get a job where you type a lot. It will make you faster, since you don't have to move as much (even if it doesn't feel like it right now, when you're just starting.)
As you may have read on some other posts (yeah, I know I mention it a lot
![Very Happy :D](./images/smilies/icon_e_biggrin.gif)
) I switched to homerow a couple of months ago. At that time, my peak was at around 70-80 wpm (with the old method), and now I've finally reached over 100. I used to type with six fingers, much like you, and at first it felt awful. Eventually it started feeling kinda natural, and now I don't even understand how I could bare typing like I did.
I would recommend you switching, if you have the time. Just keep in mind that before you start accelerating in speed, you have to get used to type with homerow method (if that's how you type). The reason for this is that if you start going up in speed any earlier, you will eventually go back to the method you were using before. Remember that your speed will not increase as much as it could if you practice the incorrect way.
Another thing I want to mention is that you do not need to get a typing software (atleast not one that costs money). If you already have one, that's fine, but it's not needed. I taught myself how to type with homerow all by myself, just using tutorials on youtube and searching good tips on how to do this.
Something else that you have to remember is that you must never look at your keyboard when you type (even if it might feel like it's gonna help.)
My speed increases with about 10 wpm every 2 weeks or so it seems. I can not say this as a fact, nor that you will increase at the same speed (because I don't know how many tests you do every day and such) but I can say that if you practice enough and correctly, your speed will increase at about the same rate.
Also, I feel that while we're waiting for the practice mode to be completed, you should take some races over at typeracer, because they have some more complex words and texts, and more a more natural way of typing (since they use real texts). Or, you could take some advanced tests. They are also good. Just make sure you don't take the same test over and over again. Because while you may improve on that test, you will not improve on other words to quickly, and therefore you will not benefit as much as you could in real life typing.
These are my tips and opinions. Keep that in mind when you make any decisions based on this text.
