Polski Daily jest bardzo dobre. I started learning Polish nearly 3 years ago with a teacher and used Polski Daily for further learning. The podcasts are great for my level as Paulina speaks slow and clear which makes it easier for me to understand. The exercises are very useful but unlike me you need to strict with yourself and keep it up and not get behind. I have recently started to use it more often now to help where i slipped, very good for learning Polish. Highly recommend
