… and we could add and add. So, that’s all for this part. We’ll come up in next one with new improvements.
Till then, try to learn from these concepts from these videos and apply it in questions. If you don’t get any questions, post it on FB groups or other forums or we’ll get back to you on that issue soon too.
Also, for practice, we’ll say you again to follow our “Where to practice?” post and solve questions relevant topic’s question on Khan academy>SAT.
