And most times, I always fail comprehension questions. I don't really know what to do dat will improve my comprehension skills.

1 A
2 B it should be 2,2-dibromopentane
3 A all of the are hygroscopic except NaOH

I really like it that we have started early to prepare and I trust that by the Special Grace of God we will have our own Testimony when the admission list will be out next year

Boss, question 10 n 12 are the same , different answers .

Pes13:


Question 10 was a mistake, a different question was supposed to be there.

ISISs:

My guy.. Get a small note book (say 20 or 40leaves) as u read, u jot down good points.
At the end of the day, u find out it is easier to cover over 85% of anyakowa or okeke (whichever suits u) within one day with ur small note that contains rugged bullets than going through the big textbook. This helps normaly wen it is a day or two to ur exam as it keeps theoritical stuff fresh in ur brain. +, ur small notes can be carried arround easily as u can at anypoint in time rush to wat u struggle to remember.
Thank u.
