Hey aspirant

Its always better to revise biology from ncert. Because each and every line of ncert is a question. So continuously revising biology from ncert test is more beneficial. You can revise physics and chemistry from your short notes along with practising more questions. You should also attempt mock tests during last week. This will help to focus on time management. You should check all diagrams from ncert. Its bettet if you tried to read short notes also.
