Schweser seems to be the most popular choice around these parts. Used it myself and stand by it. I just got the basic package, a lot of people like having access to the QBank as well though, up to you.
Wiley makes an 11th hour guide and Schweser has Secret Sauce. That’s the next level of condensed but I’d highly recommend trying the regular Schweser notes. How demanding is your job? Do you work weekends? There’s still 4 months until the exam. That’s plenty of time for L1.
