Thanks for query

Practice only from those books which almost cover the entire syllabus of the exam like Arhihant is one of the best book for bba prep.U can also go for pratiyogita darpan.

Basically there are four sections in BBA CETi. English Language & Comprehension ii. General Awareness iii. Logical and Analytical Ability iv. Communication Aptitude

You will get most of your study material in these two books.
