Chill man ! You came late but right . Yes you have to do H.C.verma oncepts of physics .Try to revise the portions of the 11th portion you find difficult.Concentrate on boards and keep the jee in mind. Anything can happen , you never know. You may get selected in jee .Try to do the competitive part along with the boards of class 12 .Endwards if you get time like study holidays , then you can focus more.
