Is Scan bot worth practicing with?

3

No, it isn't.
The reality is that starting from lvl 4 you can get advantageous positions, which can be drawn by the weakest side, if played properly. However, Scan has bad reputation for being escaper in endgames, starting from that level, while your real life opponents at same or similar ELO can easily make a mistake.
Is there better option than Scan?
Yes, there is. Checkersland (see site and Android application) has more credible range of levels.

Scan bot is hard which is ok to me. I think it's good if you get some experience under your belt.
