homecoming true; } }

this because homecoming false statement never reached if user has made no choice:

if (rda.ischecked() || rdb.ischecked() || rdc.ischecked()){}

in if else statement homecoming false later. if none selected, automatically homecoming true because code block within statement above not rached. , in timer say:

if (getnextquestion(false)) { // start timer 1 time again countdowntimer.start(); }

getnextquestion allways true if user makes no choice, timer starts 1 time again , again.
