Hii aspirant . .

Most probably there will not be much changes in the exam pattern and course in this 3 years but I would recommend you to you think about your decision once more. If you are going to appear in the exam after 3 years then there is no use of doing the coaching and preparation 3 years back from 1st year. And trust me 3 years are enough for a person to forget all the concepts and lessons that you learnt in your coaching for SSC exam .

And if you have make your mind to do the coaching then I would recommend you to continue the practice of mock test and sample question papers as it will help you to revise your syllabus very well.

Hope it helps. 

Best of luck
