すぐに means like “straight away” but if you change it to もうすぐに, that gives it the meaning of ‘soon’.
The Japanese word for JLPT is 日本語能力試験. I know this is a more advanced word than N5, but most Japanese people won’t understand JLPT. Also, instead of N5, let’s go with 5級
This is the past tense, but you’re talking about something in the future, so let’s go with 始めるでしょう。or something like that.
Hope this helps!
