				1. I didn't do well on the test. I should have studied last night.
 
2. I am sorry. I shouldn't have yelled at you last night.
 
 
In the sentences, there are present perfect(have + pp.) and past tense (last night).  
 
 
Q1. Are the sentences above correct?
 
Q2. How to change them into correct sentences? |

Both sentences are correct. Instead of calling them "present perfect" I prefer to use the term "modal perfect", and the modal perfect works fine with words that are in the past like "yesterday" or "last week" etc. |
