Actually it is good but not sufficient you must follow some other books along with this like Arihant publication books which will also help you to clear entrance exam for BTech you can also follow kc Sinha books it is also good

Many state board books are good as comparision of CBSE board books.My suggestion is Firstly match all the topics from jee syllabus with your board books.Generally any board books carries almost all the syllabus of JEE .

But only doing board books is not up to marks as per JEE entrance.You should do MP board book first as it clarifies the concept 11th also and also going to helps the build the foundation later on you should do other books but also do previous year question books of board and entrance also which is actually going to help .

Hope this helps you.
