There is nothing wrong with joining a learning centre in Singapore with two subjects, especially if you have the motivation and willingness to comply with all the worksheets and other requirements. However, be wary of these things because you need to know them first before anything else, and explore them below: 

FACT #1: IT CAN BE TIRING 

Since we are talking about additional classes after going to school in the morning, there is a possibility of being tired because things might seem overwhelming for the child who wants to take more than two subjects during after-school hours. However, it does not mean you should steer clear of them, and the point is that you should carefully think before anything else. 

FACT #2: SUBJECTS HAVE A CONNECTION

There can be a connection between your English creative writing classes in Singapore and the science programme you wish to take, despite the idea that they are two separate entities. How? An example is when the student applies their communication skills to make sense of scientific experiments or uses their aptitude for reading when trying to understand what needs to be done during practical activities. 

FACT #3: IT MIGHT DEPEND ON THE SCHEDULE

Learning centres and tutors have schedules to follow, and sometimes, clients cannot choose two or more classes because they will clash. In situations like this, you can ask them for reconsideration or make a compromise if you want to go with their learning facility. (Tip: If possible, look for an option that ticks all the boxes.) 

FACT #4: THE STUDENT SHOULD WANT IT

If you are a parent deciding on behalf of their children or making moves for them, keep in mind that mixing classes involves asking your child whether they want it. For example, tell them about the primary school programmes you wish them to join or how it would benefit their academic performance, and if they disagree, respect that decision. 

FACT #5: ONE MIGHT BE BETTER THAN THE OTHER

Since we are talking about different subjects or taking math, science, and writing together after school, there is a possibility of having different results, such as the student succeeding more in math than science or the other way around. That should not be a problem, as long as they have finished worksheets and other assignments. 

The Junior Learners Learning Centre offers Science tuition programmes in Singapore and for other subjects as well. Check their website for more information on their educational offerings.
