Hi guys I am from TN board I want to know how to clear these exam .And usually when the exam will conduct
Which exam preparation and exam date are you asking for? Please specify.
Focus on jee main preparation, maintain a time table and follow it with sincerity. You should also be regular with your study. Huge amount of gaps can bring a break in your preparation and make difficult for you to memorise.
Start with the basic concepts of Physics. It is recommended to cover all the basics of Physics with NCERT books. Memorize all the important Physics formulas for JEE Mains. In Chemistry the main topics and challenges are to memorise names, atomic numbers, symbols, atomic weights of all elements in the Periodic table, you can make some Mnemonic, short slogan or catch-phrases.
Go through previous year papers and give tests to analyse your preparation and performance.
Good Luck.
