Which option is better BIMHRD operation or 1 year gap for top 20 colleges? I have scored in class 10th and 12th: 80% and engineering: 70%.

Yes, candidates who have passed class 12 with PCM or BiPC can appear for NEST. They alos need to obtain 60% marks (55% for SC/ST/ Divyangjan) in aggregate.

In the last 14 days, students are advised to learn the most important topics. they should learn the repeated questions thorougly. They should revise all the important formulas and learn the diagrams.

Students can crack TN 12th exam without coaching. They should learn the lessons daily. Practicing TN 12th sample papers and past years' question papers will help students to get good marks. 

80 per cent or more is considered as a good score in TN 12th exam. 60-70 per cent is considered good. Students need to score 33% to clear TN 12th exam.

Students should prepare for TN 12th board exams as early as possible. They should study atleast 5 to 6 hours daily to score high marks in TN 12th exam. They must start preparing from the first month of the academic year.
