Assuming the kid is 12 year old and spends 6 hours in school for 5 days a week, that would be a total of 30 hours per week. Additionally, if the kid spends 8 hours of tuition per week, the total time spent in school and tuition would be 38 hours per week.
If the kid wants to be good in chess, it’s important to also have time for other activities and rest. A good balance is recommended to prevent burnout and to ensure that the kid can continue enjoying chess in the long run.
Assuming the kid needs at least 8 hours of sleep each night, that would be 56 hours of sleep per week. Subtracting the total time spent in school, tuition, and sleep from 168 hours in a week, we get:
168 – 38 – 56 = 74 hours per week for other activities and interests, including chess.
Since the kid is already spending 38 hours in school and tuition, they would have a maximum of 36 hours left each week for other activities and interests, including chess.
Therefore, the 12 year old kid can afford to put up to 36 hours per week into chess if they want to. However, it’s important to note that they should still have time for rest and other activities to maintain a healthy balance.
Please note there are a lot of assumptions here and just some simple math. This is not an expert opinion and different children will have different numbers of hours free for them.
