We have 1 & a half chapters left to learn but our teacher taught c4 so weird. After c3 differentiation we went to integration and did it up to integrating partial fractions then went to chapter 1 and did all of it in a lesson. Then back to integration then to chapter 2 then chapter 6 integration again to learn integraiton by parts and sub etc then we went to chapter 4 and did all of chapter 3 in one lesson yesterday and now back on integration to finish the rest of it before finally hitting vectors in chapter 5
