See I try revising but the thing is the textbook is very easy. Then I see the exam which is much harder and I get confused. In the textbook suppose we learn F=ma then they give a basic problem where they provide the mass and acceleration. But in the test they give some complicated thing that completely flabbergasts me. Any solutions?

Read the question carefully.
Try to write down the things given in question,then apply the formula.
All I can say is maybe at first it seems hard but eventually you will get used to it,hopefully.

Oh that kind of thing happened to me alot! Being honest it does now as well.
I think for those kind of questions all you can do is practice more and be sure to read the case given in the question.
Eventually,with practice you will get the hang of those type of questions.

I'm sorry.I'm not much help,I guess.

I really freak out with those type of questions. Any idea how I could practice them more or if anyone else on the site or somewhere else could help me?

ARTHROPODS include > Insects, Crustaceans, Arachnids and Myriapods.
So it will be 80+10+7=97 <There aren't any Crustaceans in the list>
Answer is B.

What year is this btw?

The small intestines of cows are similar in general structure and function to the small intestines of
humans.
A disease in cows reduces the number of villi in their small intestines.
The cows lose weight and become weak.
What explains this?
A less amylase produced
B less peristalsis
C slower absorption of nutrients
D slower digestion of proteins
