Can someone please help?:)Not sure why I keep getting an error! :(

ValueError: setting an array element with a sequence.
It seems your first list "[4.01, 3.285, 3.5]" element in the np.array only has 3 items (grades) while the others both have four. If you add another grade to make this a 3x4 dimensional matrix it works. If you don't have a grade to add, you can still make this work by simply putting 'nan' in place of the missing grade(s). Note: 'nan' is recognized by Python as "not a number" and is used to fill in missing data. It may look like a string (need to use quotes for this list item), but any string or an empty string doesn't work and results in a datatype incompatibility with your float16 type.
