I would assume you would get your equipment/supplies from a reputable supplier - one that perhaps your college is affiliated with? As for the client, you should supply them with aftercare information or leaflets to help them maintain the condition of their hands and nails at home.
LOL, the questions sound much more simple when put this way..but unfortunately, colleges would not appear professional if they were worded this way. (baffle students with BS and all that)
Sorry Tia, but these will honestly be the easiest questions in you course..guaranteed. Just make sure in class you listen, ask questions to what you do not understand, and make sure you attend every single class.
And of course..do your study
If you are stuck..arrive early or leave later, to ask your tutor about anything you do not understand.
It is her job to make sure you do learn ..whether she appears to like it or not..we all learn at different rates..and as a qualified teacher she should understand this.
