Differences between LSAT Starter , Premium and Ultimate

I-Scored-A-181

So I was about to buy a course, but I have a question.

I've noticed for the lessons, some have different amounts of lessons per. I had thought the differences were only due to how many LSAT tests were explained. For example:
Main Point & Main Conclusion Questions 17 lessons, 1.6h (Starter)
Main Point & Main Conclusion Questions 19 lessons, 2.1h (Premium)
Main Point & Main Conclusion Questions 21 lessons, 2.3h (Ultimate)

I know that upgrading from one course to another gives more lessons but my questions are:
1) Will using a starter with 17 lessons versus an ultimate for 21 lessons on "Main Point & Main Conclusion Questions" be a huge difference? What are in the remaining 4 lessons?
2) If I start using the Starter and decide to upgrade to Premium later, will my 7sage program show that I have 2 extra lessons that I didn't use?
3) Are the lessons that are skipped in Starter something that might cause the following lesson to make less sense?

Im pretty sure the extra lessons are more drill sets/explanations. 3. that would be silly

I think if you go to course, syllabus you can see all the lessons and they are color coated for which package they unlock for

You don't miss out on any Lessons. Like jdawg said, they're just extra drill sets/explanations.

A difference between the packages however are the number of full PT's provided with video explanations.

I think the main value is getting the additional explanations for actual PTs

alright got the LSAT starter kit then

That should be enough for you to get started. If you truly enjoy watching JY's explanations and feel you are learning from them, then upgrade.

But the upgrade would only add some extra drilling as well as more PT's, that's it?
Just because I already have the PT's and most of the explanations.
