The Book gives basic information. Its introduction is good.( 7-8 Pages only ) However Beyond that the writer has explained the ideas in 4-5 pages which ought to be explained in 4-5 lines. Not adequate topics covered. Also the depth is lacking... It seems its written for a country other than India. Also the syllabus for IPCE covers topic better than this...
In short, Its not worth Buy !.... Not recommended...
