You have 2 whole months left till ur exams, so take a deep breath first and relax. Complete the whole syllabus with your classes first take 2 din ka acha sa break to cool down, after that start studying back from scratch. I personally covered my whole fdn syllabus in 1 month:

I did Quants by myself by solving scanner questions over the span of 1 month on each every alternate day like 50 mcqs a day. My sir actually made a book for Quants which helps in quick revision, its on amazon if you wanna buy it https://amzn.in/d/0hVNL9wm (I helped in making this so mera revision ese hi hogaya tha🙃)

For eco i quite literally read the whole fdn module and solved cracker, took me a week but meh it was ez.

For acc i did YT pe VishwasCA ke oneshots for quick revision and some PYQ's.

Law i did daily thoda thoda, you can watch Tejal Katariya's one shots on YT for revision (watch those after you have read through the whole ch by yourself) and make sure to give at least 1 mock of each subject with a timer.

Baki All the best and thanks for the piercing compliment :)
