There are many factors to consider as you decide how long to study for the TOEFL. Check out this post from our TOEFL Blog for an in-depth discussion of how long you should study. This quote from the post should be of particular help:
If you haven’t taken the TOEFL before, use some official practice to get a better idea of what you need to improve:
- If the material seems straightforward and you’re already comfortable, you can probably study in under a month.
- If you understand the majority of the language, but have trouble with the format of the test, it may be 1-3 months of preparation
- If the general language level is very difficult for you, getting to a high TOEFL score (>90) could take years
