This depends on how much time you are willing to prioritise. Each course has a recommended study time, which we believe is imperative to complete in order to guarantee a pass in the final exam. An IGCSE or GCSE has recommended study duration of 120 hours. If you can commit 10 hours of studying per week, the course can be completed in 12 weeks. An A- level has recommended study duration of 360 hours. If you can commit 10 hours of studying per week, the course can be completed in 36 weeks.
