The main aim for a wbjee appearing student should be coverage of entire syllabus without going in depth.then ,comes the time factor i.e your ability to have speed in solving.

So,revise and prepare from the materials that u have used till now.once u r done with it,go for any objective book of moderate toughness and then at last solve the previous year papers

Based on above,i would recommend you the books:-

Phy-dc pandey level 1 or objective qstns of any reputed coaching materials or hc verma basics

Chems-organic n inorganic :NCERT n for physical:o p tondon

Maths:ncert,vikas rahi tmh,arihant level 1 problems

ARIHANT PUBLICATION PREVIOUS YEAR PAPERS i would say is MUST ,you need not to solve other above books if you have a coaching material.believe on your material and refer arihant book to understand the need of exam n practice from your material.however chems can be prepared only using ncert ,no need to go for tough materials here and there.
