Help me !!

I am a cs student in tier 3 college i have given my 2nd sem exams and now there is a holiday of 2 months till 3rd sem starts so I was confused what should I do in these 2 months I have few options -

1. start preparing for gate

2. start learning web development

3. start learning java (with dsa)

4. learn python (including automation and ai stuff)

5. start learning c++ (with dsa)

I have some familiarity with python and c but only basic level (file handling). To all my seniors can you guide me what should be best for me. My college placement was not good previous year but this year around 50 students (strength is around 70-80 students) got placed with 6 of them getting about 12 lpa package although the actual numbers are yet to come
