I did mine yesterday, we went through polymerisation of all systems in detail, different types of monomers/polymers/oligomers, MMA, PMMA, copolymers and the different types of acrylates of all three systems.
Then troubleshooting problems as in ageing, bubbles, yellowing, lifting, pocket lifting etc, why it all ocurrs and how to solve it.
Tipping was all about applying tips to fan, ski jump and bitten nails, my educator simulated these types of nails on the nail trainer and demoed how to deal with them........I was lucky enough to have this course as 121 so my model came along, tipped her which were checked and then Lyn let me finish a full set......was so pleased about that because I went from Bristol to Plymouth and I rarely see my friend to do her nails.
