Really, almost and nearly are degree adverbs, and they always come before the term they modify:
I nearly crashed my car. [nearly modifies crashed]
The fuel tank is almost full. [almost modifies full]
I really love studying grammar! [really modifies love]

11. ADVERBS OF TIME
They usually go in end position; front position is possible when I want to contrast a new time reference with a previous one.
I went to the cinema yesterday.
Yesterday I stayed up late, but today I’m going to bed at 9.30.

12. ADVERBS OF TIME
They can’t usually be in mid position, except for the following adverbs, which are often in mid position:
now, already, finally, recently, soon, still, just
I have just had lunch.
We have now finished unit 2.

daily, hourly, weekly, monthly
I go to work daily.
We write reports weekly.

even, just and only
They USUALLY go in mid position:

15. ORDER OF ADVERBS
When you have lots of adverbs in end position, they follow this sequence:
manner >>> place >>> time
She danced beautifully at the ballet last week.

16. ORDER OF ADVERBS
Another thing you have to take into consideration is the length of the elements at the end of the sentence. A long adverb (or a long object) tends to be placed after the other elements, even if that breaks the usual word order [object>>>manner>>>place>>>time]
He was arrested last week at the customs desk of Bangkok international airport.
She left at 3 a.m. with a great deal of noise.
This is extra information, so you don’t have to worry about this on yout test.
