Please use the above reference books for your preparations. If you have troubles with theory in Mathematics than you can refer M.L.Khanna old edition where you can read the problems with there solutions and try to understand their approach towards it. Still I will consider it as half measure, try to get help from your teachers and clear concepts first.
