Yes, English hotspot is very useful in scoring good marks in English in Bank exams.
Many of my friends have been following this and their marks have improved in the recent exams.

It contains compilation of The Hindu Editorials. There are 10-12 questions based on each editorial. These questions include 2-3 questions of RC, 3-4 cloze tests, 2-3 error detection/sentence improvement, 2-3 para-jumbles,etc. There is detailed explanation for each question. Explanation quality is superb. You will not get such explanations anywhere else.

It also contains compilation of important grammar rules used in the Editorials.
Apart from these, it also contains The Hindu Vocab, Idioms-phrases and phrasal verbs monthly compilations.

So doing English Hotspot is way better than just reading The Hindu in my opinion.
