It is difficult to provide a blanket answer to this question. Each candidate's circumstances are different, and their method of study, experience and knowledge of English law and general ability will determine the time it takes for them to adequately prepare for each stage of the SQE assessments. As a general guide, however, which is based on our experience with the QLTS assessments which have been the model for the SQE, we recommend that you begin your preparation for SQE1 as soon as practically possible, at least 5-6 months in advance. Devote as much time as you feel will progress your preparation. We would recommend an average of 15 hours a week. That said, some candidates progress adequately with less time put in, whilst others require more. The advantage of the QLTS School preparation course is its flexibility. You can study at your own pace and according to your own family, work and social calendar. As for the SQE2, based on candidates' experience on the QLTS, it is recommended to spend at least 15 to 20 hours per week over a 3 to 4 month preparation period.
This means that studying for the SQE is a serious time commitment, which should not be taken lightly.
