Hi Sir, I am Shanmathi from Chennai I have purchased your FR Colour summary book in Feb 2021. To be frank I have not used it coz I felt study material is good for concepts. But due to time constraint I took your book from past 2 days to prepare for FR exam. Really I felt very much satisfied. The content is very much sufficient and it has what is needed. I am reading the concepts from your book and doing Study material sums and really I could solve all of the questions. Though I could not solve I can at least relate the concepts to it. Regretting for not using it earlier. Thank you so much sir.
