Thank you!

(1) Grandma told me that if I did my school work well and read a lot, I would be able to floor a handsome young man when I grew up...

(not very sure, need to double check)
我最近发现自己动词时态上的问题还挺多挺大的，常常困惑。这个可能我原来的也行，你改的也可以。
>> what does "floor" means here? To surprise/impress?
不知道我用的对不对。be floored有“倾倒”的意思，但是主动语态是否还有这个意思我没查过，我这样随意发挥了用也不知道有没有问题。一会儿去翻字典。

(2) I did my best at school besides reading quite a lot books that wouldn't have helped me with the college entrance exam.
->
I did my best at school, and besides, I read quite a lot books that did not helped me with my college entrance exams.
我想说的是在读够了杂书之余，我尽量把功课学好。是不是下面这样好些?
Besides reading quite a lot books that wouldn't have helped me with the college entrance exam, I did my best at school.

(3) And I ended up marrying a guy who is decent looking, though far from even comparable to Song Yu, but has read a wider range of books than I.

你改的好。

(4)I recalled that old saying Grandma had taught me again.

你改的好。

(5)is it that all the bookworms are good looking, or that all the good looking people love books?
->
is it true that all the bookworms are good looking, or that all the good looking people love books?
两种说法意思不完全一样，我原来的可能也可以？
