не хватало времени спросить каждого студента
didn't have enough time to hear each student (their lesson)
there were no free time to ask every students
Полина, "time" is a collective noun and is always treated as singular. So "there WAS no time".
- "Free time" means "свободное время", as in "what do you usually do at your free time?"
- You can't ask every studenTS, you can ask every studenT.
Tatiana, it should be "I didn't have enouph time", not "time enouph". "Time enouph" is not commonly used in everyday speech and usually has a different connotation. Normally "enouph" goes before the noun.
Oh, Olga, you are, of course, right. I shouldn't have done it today, because of my splitting headache.
