Put in your start date and every day of the 8 weeks gets its date: a lesson Monday to Friday, a revision on Saturday, a mock interview on Sunday, then 12 bonus mocks. Mark each day done and it turns green; rate how sure you feel; the first tab shows what's next and how far you've come. The DSA tracker has 140 classic problems grouped by pattern, each linked to LeetCode, and the mock log scores every interview on the seven things interviewers score. Opens in Excel, Google Sheets (File → Import) and Numbers.
