Give maximum 5 to 6hrs(i know its too much) for self study(does not include h.w). First complete the subject which u feel easy... then do tough chapter. As soon as it is completed in class come home revise that topic and solve questions from that topic. Every saturday make a question paper ur self from guides and write that test(or as a worksheet) on sundays....this will keep u revised of all the topics...

Vidushi Shukla 6 years, 5 months ago

Its easy but lengthy. If u r doing by elementary row operation write A = IA Now write the given matrix in LHS 's A not in RHS 's A . Then try to make the LHS matrix as identity matrix and do the same changes on right side and u will end up getting the inverse.
