Spreadsheeto is saving me hours and hours! Kasper is clear in his directions, it is in short segments with practice in between each, and a review at the end where I find out what I need to practice more. So nice I can go back any time to review. This was an investment in myself and it is paying off beautifully and quickly. Also, I decide when I do the course; I love that flexibility. I highly recommend this course to anyone who uses Excel regularly.
