How do I work with CT ART?


Should I use it by theme or by difficulty level, and one more thing how many tactics should I do every day, I mean I was wondering if there is any particular method! Thanks everyone.

CT art is a very good chess course available on Google play I think u should first solve all the tactics by themes because in chess it is very important to learn tactical pattern after solving each of them u should go to test mode and test yourself I recommend you to use CT art chess tactics 4.0 this app is for 1200-2100 rated players and I also recommend u to buy whole coarse u should have serious improvement after solving it for several weeks
