Absolutely. The CrunchPrep course is very flexible and can be used as you like, and according to your needs. You can find a variety of study plans in the Resources section, and you can choose the plan that suits your needs the most.
All the study plans are provided as spreadsheets, so you can also make necessary changes to the study plan based on your daily schedule, your requirements, and your target score.
For example, if you need to study for 1, or 3 or 6 months, you can find the respective study plans directly in the resources section. However, if you wish to study for, say, 3 weeks, or 5 weeks, then you can make suitable changes to the plan on your own. For example, if you are already confident about Word Problems and want to spend a loss less time on it, then you can allocate more days to a weak area and balance the plan.
