Hi Sama As a native English speaker, I feel that there are various options which, according to your situation, could be "most correct". If,however, you are wanting to tell somebody whom you know well about the changes that are happening in your life, then it would be best to use the following option: I have almost completed my IT course and am planning to begin an English conversational course. If,however, you are planning on using this sentence on something such as a CV, it would be best to use the word "a" rather than "my" [IT course...] I hope this helps!

your sentence is correct!

I have almost/almost finished (my) IT course and I'm planning to take.... I think your sentence is correct...hehe..good job :)

I finished IT course and I'm planning to take/do English conversation course .

I almost finished IT course and I'm planning to take English conversation course .----I've already finised IT course, and I'm going to take English conversation course.
