You should solve a solved book which would help you in doing any type of question and remember that their should be a variety of questions, not similar type of questions which will help you in future in tackling varieties of questions without any problem.
						

							
i think u should solve CONCEPTS OF PHYSICS BY H.C.VERMA and also the book named problems in general physics by I.E.IRODOV
						

							Follow the pradeep`s physics book or h.c verma or s.l arora book ..mif you want to do good in your board exam only then read only those topic which are in your syllabus...otherwise read the whole book,it will help you!
						

							The book of arihant publication,written by d.c PANDEY is the best book covering all the  syllabus and the book is really helpful .

HC Verma is Physics Bible. If your physics is weak, restrict yourself to HC Verma and DC Pandey. Don’t solve IE Irodov, so early. They contain high level problems. First solve these two books thoroughly. Then try Irodov. You should also solve previous years JEE question. Good luck :-)
 
 
						

							If you want to stronger your concepts go for hc verma physics or concepts of physics by hc verma .Dont solve ie irodov if you have less time solve only limited no of problem but solve with clarity
						

							
Brother, if you are having conceptual problems in physics, then FIRST study NCERT textbooks. After that I would recommend you to study HC Verma. If you think that you have mastered the content of the chapter which you are currently reading, then solve problems from IE Irodov for challenging questions of that topic. Further, you can solve DC Pandey if you have time left. 
Remember, your fundamentals about any topic should be clear.
BEST OF LUCK!
