I was able to pass without the seminars on my first attempt at BS (I wanted to take them but couldn't afford to), but I did purchase the Amber book. If you would like to take a peek there is a youtube channel with some of his videos. It looks like the electrical video (about 19 minutes) that is posted might be part of the seminar. The Amber book, on the other hand, is not that expensive, you can probably buy a used one for a decent price and I would definitely recommend it.
So, in my opinion, it is possible to pass without purchasing the seminar but if you can afford to pay for them it is probably worth it.
