There are not many short cuts (Infact I do not have any.) But you will have a number of tricks (L Hospital is a trick which people call a short cut.)

Tricks are the special step which you take for a particular question (Just to make its simplification simple.) The various cases discussed in NCERTs and your coaching material are such tricks. Follow all the tricks mentioned in your coaching material. They are enough.

Please rate me.
