I am diploma student..how can complete the full syllabus of 1st and 2nd year only 3 months?
Check previous year papers. You will get to know the topics that carry weightage. study them well. Also check the other subjects. 3 months is enough if you study well unless you think of syllabus in terms of years. Break the subjects and start studying diligently. You should get very good marks. All the best!
