Thank you very much Julio for taking your time out on providing this extensive feedback. This is very helpful as I have been approaching this for quite some time, but due to work and other commitments have not had the opportunity to remain steady on my readings.
I believe you are absolutely right about building the interest, which is there but I guess allocating the time for it is key, at least on my end.
Btw, I have been utilizing Whizlabs, but the memorization may not be quite effective so will review your other resources and attempt to take the challenge patiently.
Thanks once again!
