Hi,
I was same as you, a complete beginner wanting to train in Bio.
I did Bio's manicure course and it was a complete waste of time (but think maybe that was more to do with the quality of the trainer's teaching), but it was a means to an end and got me on the Bio gel course so was worth it I suppose.
I will say that I thought Bio's manicure tools and products are really nice so it was worth it to get the kit so you can offer basic manicures alongside gel treatments.
Hope that helps!
