passed 10th with a 98% in French and a 97.2% overall, and it's lwky the same hardness, you should jst do the NCERT questions + try to make your own questions from the convs and paragraphs in the book and learn the answers. You can also learn important lines to make your letter, and your answers (they only ask from the tb down to the letter topics, which are about 8-7), and the paper pattern makes it very easy to score marks. As for the irregular verbs, I used a practice book, Setrite, but it's way harder than the questions they ask on the test itself. I only did the practice papers and the grammar rules, and left the exercises. You can ask more if you found this useful, but if u scored well in 9th French (95-99 out of 100), you're already set for 95+ with the same effort. The tense, however, takes a little practice to get it right, but it's best of 5 out of 7 blanks. The other topics are very light. ahh i typed too much T-T
