Hi Mradula !
Basic Psychology is all about the concepts that are fundamental to the study of human behaviour. Memory, attitude, perception and personality are some of these topics.
Basic Psychology also covers the history of evolution of psychology as a discipline by chronicling the schools of pshychology such as psychoanalysis , behavioral psychology and cognitive psychology .

Applied pshychology has to do with the applications of these concepts and involves experimentation and psychological intervention. In simple words, basic psychology is heavy on theory and applied psychology is heavy on experiments and the implementation of psychological theory to deal with real life issues.

Hello Mradula,
Psychology is vast subject with lots of branches and specialities. The best way to spot the differences between the two is to look up the course details on the website.
General psychology: is where you can learn about facets of mind, various theories which have shaped the course of psychology.
Applied psychology: is where one learns to put  the theories and principles of psychology to practical and tangible use of everyday world.
Hope this is relevant.
Good Luck.

Hello student,

Applied psychology is the use of psychological methods and findings of scientific psychology to solve practical problems of human and animal behavior and experience. General psychology is the study of the basic theories, principles and methods of psychology, which is the study of the mind.

Cheers!
