aslamu alaikum. Respected seniors and members
i am confused a little bit as about only 6 months are left in CE-16
i am not proficient in English and vocabulary is also not that much good which is necessary for CSS. But i think 3500 words of Barron's vocabulary would be sufficient in sha Allah. Also I guess it is so difficult to memorize and retain all of them in this six months period along with other subjects
but I have good background in Everyday science, Islamiyat, Islamic History, law and jurisprudence (because reading is my from very childhood alhamdulillah)
NOW what should I do?
should I go for CE-16 with poor preparation, just to experience the whole procedure and failure
or prepare for CE-17 and take the test with satisfactory preparation?

Kindly guide me in this regard.
Thank you
