I would recommend not overworking yourself too much cause burn out is very hard to get over. That being said, the more PT's you do (and blind review) the more improvement you'll be likely to see. It is definitely a lot but doing 4 pts a week helped …
I may be taking the LSAT in a study room at my local university, the Wi-Fi is better there and it is much quieter than my house. There are also computer rooms there if my laptop has a poor connection.
