Recommendation to keep skills fresh

I studied for the CCNA by watching mostly Jeremy's videos labs and flashcards and a bit of practical networking. I've been exam ready after about 8 months of study but I have had no luck being able t pay for this (funnily enough i was gonna take the net + first thinking it cheaper lol)

I have no idea when or if I'm even gonna be able to pay for it but how do i keep my skillls fresh? Labs and the like have gotten pretty monotonous
