Going from Network+ to Security+

Any advice on studying for the Security+ after passing the Network+? I have just purchased Andrew Ramdayal’s course on Udemy due to him being extreme help with my n+. Just wanted some in-site with the difficultly, time length (average) etc. For context it took me 3-4 months for the N+ of on and off studying due to life and I passed with an 818. Thank you in advance for any input!
