How do you design this circuit? Design a simple oscillator circuit using the 74HC04 hex inverter IC. The oscillator should produce a square wave output with a frequency of approximately 1 kHz.

You need to show your best attempt. We can then help guide you toward a solution. That's how you are going to learn the most -- remember, we won't be a resource you can use on the exam.

The 74HC type of Cmos logic has a high "shoot-through" current that can be or can exceed the maximum allowed output current.
Therefore I think an ordinary old CD4069 oscillator should be used that can very quickly switch a higher current 74HC04 inverter if the higher current is needed:
