What I have just noticed with your online course is somehow different comparing to other online where by the other's online they gives an assessment after completing every section so that to test yourself and you have to pass all the questions before procceding to the other section if not you won't be able to go ahead. Therefore this paves the way to pass the final assessment test at highest degree and also helps the candidates to be familiarized with the probable questions which may arise either in the test or at working place so for me having that previous experience from the other online teaching institution I suggest you can just do like them for your nearest future. Thank you in advance and keep going.
