Should I trust this PDF blindly nd skip every single topic that is not mentioned?

Like for example - In polymers, they asked to cover - Natural plomers, cellulose, teflon, bakelite and pvc only

Shouldn't I skip to revise structure of other polymers?

Every time I attempt test tries to submit it always stuck on the loading page when I reopen the website

I have to reattempt the test and then it submits

Anyone else facing the issue !

Help me out 😞 😭
