IB students must decide whether to study a subject at Standard Level (SL) or Higher Level (HL). It is therefore essential to understand the differences between these options. In this post, we will provide a thorough breakdown of the distinctions between SL and HL.
IB SL vs HL
Difficulty
Higher Level subjects in the IB are generally considered more challenging than Standard Level courses, despite what some statistics may suggest (for example in Math AA, a higher percentage of students earn a 7 in HL than in SL but this is mostly due to the fact that students which decide to take Math at HL are generally more proficient in mathematics from the outset and aim to pursue math-related courses at university).
HL subjects are generally more challenging. HL subjects cover a significantly higher amount of content which is also often harder. Many HL topics expand upon the concepts learned at the SL level, but with greater depth and complexity. For instance, proofs in Math HL demand a deeper level of understanding and advanced problem-solving skills compared to those in SL. Similarly, HL Biology delves into SL topics with far more detail, resulting in a significantly larger volume of content that HL students must master and retain.
Sometimes, HL papers may also be inherently more challenging. For example, in IB Geography, the HL paper (Paper 3) is regarded as much more difficult than the SL papers (Paper 1 and 2). In Paper 3 HL students must complete two extended response essays in just one hour, which requires not only a deep understanding of the material but also excellent time management and essay-writing skills under pressure.
Contact hours
Higher Level subjects require significantly more time than Standard Level due to their increased content and complexity. In class, HL courses often cover more material at a faster pace. Outside of class, HL students must spend more time reviewing, practicing, and completing assignments, as the content is more challenging and in greater depth.
Which should I choose?
When deciding between Standard Level and Higher Level, it’s important to consider several factors. First, remember that HL subjects require a significant time commitment. If you don’t particularly enjoy the subject, taking it at HL may become frustrating, as you’ll need to dedicate considerable time and effort over the two years to keep up with the workload. If you find the subject difficult or lack interest, it can quickly become overwhelming. You should also assess whether you're capable of handling the subject at HL. For example, if you’ve never been particularly strong in math, taking Math HL may not be the best choice, as it is much more challenging than SL and could cause unnecessary stress. It is also very important to think about your future university plans. Many universities have specific requirements for HL subjects, especially for competitive courses like Medicine, which often require subjects like Biology and Chemistry at HL for admission. Hence, be sure to check the entry requirements for your desired course to ensure that you choose the right subjects at the right level.
