Thanks! Another question is... Have you tried the Amscope prepared slides sold on amazon?
I am referring to this ones:
I had a good experience getting some prepared slides: https://www.amazon.com/AmScope-PS25-Microscope-Biological-Education/dp/B0055DZ3EK/ref=sr_1_1_sspa?ie=UTF8&qid=1543639766&sr=8-1-spons&keywords=prepared+slides&psc=1
This way you can focus on working the scope for a bit and familiarizing yourself with the controls scheme.
