What to study now?

Question

Objective-C

Good afternoon! I understand that similar questions are asked here a million times a day and my situation is not at all unique, but I still dare to ask a question. I have already built a defense against flying sneakers)
Nevertheless, to the topic. I worked for about 1.5 years in a company specializing in microsoft dynamics CRM. The work was strange, there were few projects, and those that were - boring. For myself, I decided to go into mobile development for iOS (which I already asked about here), and, having actually saved up money for food and so on, I quit in order to finally deal with term papers at the university and start a "new" life. Yesterday I sat and studied algorithms - O-symbols, growth of functions. I already know elementary data structures like a stack, list queues. In the process of reading literature, watching videos and solving problems, a reasonable question arose - is it worth spending most of the time on this now? No, I certainly understand that algorithms are super important, but is it so important to study the growth of functions and the analysis of algorithms right now? Or is it worth going deeper into objective-c - write a couple of applications and get a job? And algorithms to leave for "weekend/evening"? I pulled up discrete mathematics - I studied sets, graphs and other subsections of the discrete while I worked in CRM. I am also reading McConnell and the Gang of Four. Please tell me where to put all my energy right now.
Don't hit hard.

Answer 1

That's what it's worth doing
Not for the evening, but for when you need them

Answer 2

Or maybe dance from the stove? =) What is the specific goal? Do you want to work in a company with interesting projects? Well, choose a specific one, take a look, or better yet, ask the company itself who they need, what skills are required, what to do and go ahead, train.
