Attend every class regularly. Pay attention to secure good marks. Do not be afraid to ask for clarification, if anything is unclear. Do assigned homework periodically. Even if the homework is experimental, you will gain by practice. Practice alone will improve your skills to the anticipated level in order to qualify in the examination. Make a selective review of key concepts. Your last-minute approach will elevate you to master the techniques with ease, provided you keep them handy. Review regularly to gain good marks. The most critical time to review the concepts you have learnt will be right after learning them to assimilate the material. Have some fun. Take time out to relax. Exercise will enable you to marginalise on gain for better marks.
