4) Grammatical range and accuracy
It is vital to use grammar accurately; this includes correct use of 
tenses
, 
active
and passive voices
, 
subject-verb agreement
, 
conditionals
, 
modals
,
prepositions
, 
articles,
and various 
sentence structures 
in both writing tasks. A
thorough review of all these grammar points is strongly recommended to
achieve a high band score for grammar. There is a quick look at each of these
aspects of grammar in the following pages:
Tenses
Depending on the type of writing, various tenses, such as present simple, past
simple, present perfect, present perfect continuous, or future tenses, might be
required. In most cases, a combination of a few tenses is dominant in a single
piece of writing, and in this case, a smooth transition among them is
essential.
For example
In summer, sales usually soar, but the state had announced a sudden
drop in sales a few months before it happened; however, based on
current trends, they will increase gradually by the end of the year.

past simple, and future tense in the above example.)
