What note do you need this week?

Monday, so: which note would make this week easier?

Reply with the level, the subject and the chapter — "Class 11 Physics, rotational motion" or "BCA 3rd sem, DBMS normalisation" — and the people who have it will know exactly what to upload. A vague request gets nothing; a precise one usually gets answered within days.

If you have the note someone asks for below, upload it and reply with the link. Your name stays on it for as long as it is read: https://www.ideatopic.com/upload
