I purchased the Extramarks course ""NEET Crash Course"" for my daughter, she get excellent features and content to study there. She will be preparing for her NEET the next year, so I am looking forward to buying that course from Extramarks since it has really done a good job this year. At last, I would like to mention that I personally never felt that my daughter is not getting solutions for her questions through Extramarks, she always gets quick answers to her queries and that is a really good service!
