I've been looking into SQL for the past few days and I've been following a few online tutorials as I literally have no programming knowledge or experience at all. I've been following the Khan's Academy tutorial and all was going well until I hit the Gradebook Challenge question, linked below.
I've had a complete mental block. Any ideas as to what commands I should be using at this point? Obviously I need to round up the decimal to a percent via multiplying by 100 but what is the actual SQL formula for this? Any info would be much appreciated. Thanks for reading.
