There are two parts of starting early in your learning. First is when you watch YouTube videos that explain concepts of a particular discipline. This will give you some foundational knowledge before school starts. You do this during school holidays when all you do for example is watch YouTube videos. You might as well add these videos to your playlist. This means that you need to know what subjects you’re taking in the next school term. The second part of this technique is to draft your learning plan based on the list of subjects you are meant to take in the next term or semester. You do this exercise, two or three weeks before the teaching period starts. Know the topics to be covered for each subject.
The main reasons of this technique is not just to get ahead but also to have ample time to review at least twice later towards preparing for assessments and examinations. The first review must cover only the basics of each topic. Do not delve into the variations from the basics during the first review. Why? Because you may not have enough time for the other topics. I learned this the hard way. You may review exceptions from the general rules later. For example, in criminal law, the rule in double jeopardy is that once someone is convicted or acquitted of an offence, he or she can’t be tried again of that same offence. This rule is based on common law. There are exceptions to this depending on which jurisdiction you’re talking about. If this is in Victoria, Australia, exceptions are embodied in the legislation. Some of them include cases when the person is charged and convicted of a lesser offence arising out of the same circumstances; or when the Director of Public Prosecutions applies to the Court of Appeal for an order to set aside previous acquittal before proceeding to prosecute because of fresh and compelling evidence. There are other exceptions but if you spend too much time during your first review, you may not have enough time to review other topics. The second review is when you go through the exceptions to the general rules in more detail.
