Dear student,

Its really good to see that you want to prepare for IIT.

Now that you are in class 10th right now i suggest you to focus on your boards for this year. But clear your basics from here only. Keep all the formulaes clear. Once you come in class 11th join a good coaching for 2 years. Practice solved papers. Do slef study for at least 2-3 hours only for the IIT.

All the best. I hope this was helpful to you.
