There are three parts in TOEIC Reading Test.

1. INCOMPLETE SENTENCES

In order to do well in this part, you should know the different parts of speech and how to form a grammatically correct sentence. Particularly, you should be careful of:Two-part phrasal verbs, Incorrect use of prepositions, Incorrectly placed adjectives, Incorrect word forms, Incorrect grammatical tense, Incorrect transition word such as however, furthermore, etc., Incorrect conjunctions such as and, but, etc.

2. TEXT COMPLETION

The strategies used in this part are similar, for example, to those used for Incomplete Sentences above. The difference is that because the blanks you must fill in are part of longer pieces of writing, such as letters, you need to keep not only the grammatical aspect in mind but also the context and tone of the entire piece of writing.

3. READING COMPREHENSION

As in all reading comprehension exercises, a various skills are required to choose the right answer. These are skimming, scanning, paraphrasing, and understanding vocabulary in context. You can identify synonyms and implied information. 

A clue is that the order of the questions follows the order to the information in the reading passage. This should save time when scanning for specific details. Make sure that the answer you choose answers the question, as many of the answer choices may simply repeat information in the reading passage. 

Lastly, you might prefer reading the questions before skimming the passage, to give you a better idea of what's to come. Complete many practice TOEIC reading exercises to familiarize yourself with common reading passage topics.
