Caught between two stools:

4. ON TIME
On time means that there is a specific time established
when something is supposed/expected to happen, and it is
happening at the planned time.
If you say “He’s always on time” it means he is punctual; he
always arrives at the correct time, he is not late.

5. EXAMPLES:
 My job interview is scheduled for 4:00 PM.
If I arrive at 4:00 PM, I am on time for the interview.
 The flight is scheduled to leave at 10:30 AM.
If it leaves at 10:30 AM, the flight is leaving on time.
 The class is supposed to start at 9:00.
If it does start at 9:00 with no delays, it is starting on time.

6. IN TIME
In time means that something happened at the last
moment before it was too late; before something
bad would happen.

7. EXAMPLES:
 The accident victim was seriously injured; they got him to the hospital just in
time.
(If they hadn’t arrived at the hospital, he might have died)
 I missed the opportunity to go to that college because I didn’t submit my
application in time.
 I left home early and arrived in plenty of time to catch my flight.
I got stuck in traffic and arrived just in time to catch my flight

8. IN THE END
is similar to finally or eventually. Use it when you are saying what happens
finally, after everything has been thought about or discussed:

9. EXAMPLE:
✗ He had promised to share his prize, but at the end he didn’t.
✓ He had promised to share his prize, but in the end he didn’t.
In an ideal world, teenagers would talk openly to their parents who
would in the end respect their child’s decision.

10. AT THE END
At the end means in the final part of an event or period of time, and it is
mainly used in the pattern at the end of.
