During the semester, I struggled at first, but I managed to catch up with my classmates by studying every evening.
Fix the pattern
One small grammar move makes it sound right.

Say: I need to catch up with the others.
'Catch up WITH' someone to reach their level (or 'catch up ON' missed work).
Which sounds natural?
Tap the one a native speaker would say.
