Hi aspirant,

See JEE main is are very competitive examination and cannot be completed successfully without knowing the the contents of class 11 as it consists about 50% of the total syllabus. As of my understanding you would appear for the JEE main examination this year and are not confident of your preparation level completely. At first you should be confident of what you know already, further as you know the first session of JEE main would be held most probably in March and consequently the last session would be conducted in June so there is still a lot of time left for it. You should start from the most important topics that are asked from the class 11th syllabus and solve all the previous year questions. Also go through the preparation tips of our experts at https://engineering.careers360.com/articles/jee-main-preparation-tip
