Is CT Art sufficient for tactics?

Is CT Art 4.0 plus the tactics trainer of chess.com sufficient for tactics improvement? or is it essential to get books such as Bain's chess tactics for students and Combination Challenge ... etc

Depends on how familiar you already are with the basic tactical motifs.  You might want something like Susan Polgar's Tactics for Chess Champions or Bain's book to get an overview of the common motifs and then drill with CT-Art and Tactics Trainer.

Thanks. Will start with Bain's book then

You might also want to get a book on endgame tactics as CT-Art and Tactics Trainer don't have many endgame puzzles.
