Welcome Senior 4!

Hi everyone!

It’s our 2nd year in preparation for the IGCSE exam so one of our challenges will be about recycling what we studied in Senior 3. There are 3 main topics this year:

1- Human body
2- Plants
3- Living organisms and their environment

For each class you will be expected to bring last year textbook and the Booklet with exercises. Get your blog ready with the Biology category. All blog assignments should appear in the category and, as well as tests, will be posted in the class Calendar.

All the best for this year!
