Maintaining vocab when time is short

I've been hit with a massive workload lately and it's killing my study flow. I've found that doing small batches of reviews during my commute is way more effective than trying to catch up later. Consistency keeps the memory fresh even if you're just skimming. I also stick to words I'll actually use to keep things relevant. It's better to master high-impact terms than to fail at a huge list when you're tired.
