Days before the CBSE Class XII examinations take off from March 1, The Telegraph spoke to some schoolteachers for last-minute tips they had for their students. Their top suggestions - students, revise well; stay hydrated;and carefully go through sample papers.

Ipshita Sharan (English), St Michael's High School: Leave out the chapters you did not understand and just revise the clear ones. There is no need to be overburdened before the exam. Eat healthy, including green vegetables and fruits, and drink as much water as you can. Instead of going through guide books, read summaries of chapters, names of poets and poems, with their correct spellings. Students must attempt the literature section and grammar portion first before taking up the writing section as it takes more time than the others

Reiju Singh (chemistry), Notre Dame Academy: Take the help of short notes to cover all the topics during revision. Solve the sample papers and take a look at previous year's questions. Thoroughly revise organic chemistry, reactions, conversions, various block elements, numerical and kinetics as these are main portions. Read the questions carefully before answering and leave two-three lines between answers so that you can later utilise the if you need to add to them

Sanjay Kumar (mathematics), Delhi Public School: Give preference to NCERT books to learn the formulas they will implement in their solutions. Calculus is a major portion but also give importance to 3D geometry, integration, vector, relation and linear programming. Attempt those questions you can easily solve for better time management, and do not bother about the sequence of the questions

S. Mohan Jha (commerce), Gyan Niketan: Go through sample papers and questions of previous years while revising but do not burden yourselves with topics you have not understood well. Answers need should be to the point, so do not fill up pages with gibberish. If a question carries one or two marks, then it should be answered as such - in a line or two. Long questions should be supported with diagrams and tables. Keep the rough work along with the solutions

Kundan Kumar Singh (physics), Loyola High School: There are 26 questions and I suggest, start answering from the last question. In this way, you will most certainly attempt the questions carrying more marks. Stress on a few chapters such as electrostatics, current electricity, optics and electronic devices. Take the first 15 minutes to read the questions properly and circle the ones that you find difficult. Support long answers with neat diagrams and labels
