*Look I*am a fourth year student in English Arts .I guess Criticizing is not a hard thing as I never studied it before exam
first see if the text is talking about any of these topics
colonization
slavery
feminism
criticize according to your understanding
first paraphrase what you have understood .Put the sentence that you are going to analyze between two inverted commas then give an analysis of what you have just written .make your Doctor feels that you are aware of what you are writing .Try to convince him.
use heavy words and complicated sentences as they like the complicated sentences
good luck isa
