I would like to inform you that for preparing for TISSNET you have to keep in mind that most of the students easily able to attempt the English and mathematics section in TISSNET. The section which troubles the student most is the GK section. So, you must start preparing for this section as soon as possible. Non-Management exam students can also crack quant and logical by preparing diligently. Work on General knowledge by reading newspapers daily and note down the important dates and events. And also read current affairs. Another potion to look after is English proficiency and for that you have to improve the vocabulary, read regularly. Pick anything which is informative and interesting. And for grammar portion read grammar rules form any book and start practicing the questions. Moreover while reading, focus on sentence framing and grammar. For mathematics and logical reasoning or quant, revise and practice all the topics given in the syllabus. Follow these instructions properly. Keep studying and keep growing.
