Hi,
I did my initial course with others and I decided It wasn't enough, I got the Gina Wallace videos and done the training as per the video and advice in my own time and I felt I learnt a lot more and I bought the training hand which I still use today, recently for my nail art, but I'm still taking courses and still learning. I think the more info u get from others, here and from the nail geek thru tutorials and with their expertise this is a brilliant site. I still have a lot to learn, but that's why I seek advice on this site.
Hope this helps
