Second time taking LSAT, seeking advice and answers to few questions

ireland.lesley5

Hello!

I took the test the first time July 2019 right when they began to switch to digital (I had a paper test) and got a 163. This was after only a month and a half of studying, using only 7Sage and I improved from a 154 diagnostic. I am looking to take the test again before applying this fall and would like to improve my score to either high 160s (168-169) or to the 170s (which obviously would be ideal). Ideally I would take it in April (before I have to start going back into work). So I have a few questions:

1) Has anyone used 7Sage again for a second test and do you have any recommendations? Should I redo the classes? Only take tests? Just seeking experiences from people who used this program twice. I loved it so would like to continue to use it, but only if people found it helpful a second time around.
2) How many practice tests should I try and take from now until April in order to likely to be prepared to improve as much as I would like to?
3) Do people recommend private tutors? Or other types of extra help?
4) Do people find the Flex test easier with it being shorter?
5) Any recommendations from people who studied while having a full-time job? (I work 9-6 M-f)

Thanks in advance for any help or advice!
