Tips for writing a review paper?

So I am a final year undergrad and due to this once in a lifetime pandemic we are now supposed to a write a review paper instead of our final semester project. I am a total newbie to the world of writing review papers or any papers in general and would love if any of you guys had any advice for me. I am basically looking for the what to avoid while writing a review paper and what from your respective experience is the best way to go about it. Thanks in advance.

P.S. I have a month and half to complete this before I present it in front of an external invigilator and he grills me.
