Can someone tell me if this sentence is ok? Or give suggestions on how I can make it better?
The students not only raised money during the walk-a-thon but continued to collect pledges three weeks afterward.

You could make it clearer by writing that they continued to collect pledges FOR three weeks after the event. As it is, did they wait three weeks to collect the pledges?
No, they collected them for three weeks after the event. Thanks for your help, Reed!
