If you have time on hand to read up on right brain training and have the determination and discipline to teach your kid yourself, then you don’t need Shichida.
If you need some form of pushing, like me, and the money to spend, then I will say why not give it a try. Don’t just go for the result but rather enjoy the process and bonding with your kid.
Ds1 was with Shichida for 5 terms before we quit. We didn’t continue because I wasn’t doing much home practice with him to achieve significant result so felt it would be a waste of dh’s hard earned money.
We didn’t enroll ds2 because I thought I could just do it myself at home…but it never happen because of my lack of determination and discipline.
Then, when ds1 was in K1, we sent him to a maths program and he went through an entry assessment. We were told ds was pretty advance for his age. The teacher asked if we have done anything with ds at home and I told her nothing except that he attended Shichida for a while. She told us that could be it because her daughter was with Shichida as well and she is doing very well now in primary school.
I can’t say for sure it is because overall, ds1 is just doing average in his childcare centre but he is indeed a faster learner compare to ds2. So to a certain extent, I do feel guilty for not sending ds2 to Shichida.
IMO, just do for what you believe is good for your kid and have faith because you may never realise the benefits gained. What is most important is that you and your child enjoy the learning process together.
