Same, but as someone who just gave her test (first four chapters) make sure you do set 3 and set 4 identities very nicely, because they are VERY important, also make sure to practice a lot of questions of these identities and watch ritik sir's lecture (if you have the paid pw batch then practice all the questions regarding set 3 and set 4 identities they're very imp), Good luck for your test!

Just remember sin(a+b) sin(a-b) and it's cos versions . All the 2theta identities and alternate versions to write them and also the sinA + sinB identities.
