IELTSSolid T2 structure at 7; T1 grammar is dragging you to 6 overall.
This is a Band 6.0 response overall. Your T2 argument is well-structured with a clear position and balanced bodies. The gap is T1, frequent verb errors and weak chart vocabulary pull it below your T2 level.
Time spent on each task was roughly right for the weighting: 18 minutes on T1, 38 on T2. What matters more is the gap in quality between them.
Your lexical level actually IMPROVED in T2, 'expand their horizons', 'flexible', 'specialist' appear in the essay you wrote second. T1 lexis ('go up', 'drop down', 'fall down a little bit') is well below your real range. This tells me T1 isn't a vocabulary gap, it's that you haven't drilled chart-language specifically.
Grammar control is uneven across tasks. T2 produces some clean complex sentences ('When an engineering student learns about business or psychology, they can understand...'). T1 has SV-agreement and tense errors in nearly every sentence ('chart show', 'it go up', 'they not change'). You can write past tense correctly, you just didn't in T1.
Your fastest lift is T1 chart-language grammar and vocabulary. Drill past-tense movement verbs (rose, fell, climbed, dipped, plateaued) and 'million' as uncountable after numbers. Your T2 already shows Band 6.5-7 control; T1 is dragging the overall band down half a point unnecessarily.
The chart below shows the number of households in the US by their annual income in 2007, 2011 and 2015. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

You give an overview and cover all five bands with figures, but the overview misses the key feature, $100,000+ was the most populous band in every year, not just 2015. You also misread the lowest band.
Logical paragraphing with overview, two lower bands, two middle bands, and the top band. Linkers ('After that', 'Finally', 'For the other incomes') are functional but mechanical.
Limited chart vocabulary: 'go up', 'drop down', 'fall down a little bit', 'not change very much'. No 'fluctuated', 'remained stable', 'peaked'. 'Millions' used as countable repeatedly.
Frequent tense errors ('chart show', 'household have', 'it go up', 'it drop', 'they not change', 'must to study'). Errors are pervasive but meaning survives, Band 5 GRA descriptor verbatim.

The chart show1 the number of households in the US by their annual income2 in 2007, 2011 and 2015.
Overall, we can see that the $100,000 or more income is the highest number in 2015. The $75,000-$99,999 is the lowest number in all the three years.
In 2007, the household have less than $25,000 was3 about 25 millions4. In 2011 it go up to near 30 millions5. After that it drop down to 28 millions6 in 2015. The $25,000-$49,999 income have 27 millions7 in 2007, it also go up in 20118 to 30 millions and drop in 2015 to about 28 millions.
For the other incomes, $50,000-$74,999 and $75,000-$99,999 they not change very much9. $50,000-$74,999 stay at 21 millions10 for 2007, 2011 and 2015. The $75,000-$99,999 stay at around 14 millions11 in 2007 and 2011, but it increase to 15 millions12 in 2015. Finally, the $100,000 or more start at 29 millions in 200713. It fall down a little bit14 in 2011. But in 2015 it increase very fast to more than 3315 millions.
Some university students want to learn about other subjects in addition to their main subjects. Others believe it is more important to give all their time and attention to studying for a qualification. Discuss both these views and give your own opinion.
You address both views and state a clear position in the intro that holds throughout. Both bodies present extended, supported main ideas. Some over-generalisation ('employers usually look for experts').
Clear progression: intro-position, on-the-one-hand, on-the-other-hand, conclusion. Cohesive devices ('Firstly', 'Secondly', 'Furthermore', 'Therefore') used appropriately, occasionally mechanical.
Adequate range with attempts at less common items ('expand their horizons', 'flexible', 'specialist'). Some inaccuracy ('many time', 'goes down' for industries). Communication not impeded.
Mix of simple and complex forms, conditionals, relative clauses attempted. Errors ('many time', 'must to study', 'a person only knows') noticeable but rarely reduce communication. Band 6 verbatim.

In universities, there is a big debate about what students should study. Some people think that students should pay all their attention1 to their main major, while others believe that learning about other subjects is better. In my opinion, I agree with the second view because it gives students more skills for their life.
On the one hand, giving all the time to the main qualification has some obvious benefits. First of all, university exams are very difficult and require many time to prepare2. For example, a medical student must to study hard3 and do a lot of practice in the hospital. If they spend time on extra subjects like history or music, they might fail their main exams or get lower grades. Furthermore, getting a high score in the main subject is the most important thing to find a good job. Employers usually look for experts in one field, rather than people who just know a little bit about everything4.
On the other hand, learning different subjects can be very useful for young people. Firstly, it helps them to expand their horizons. When an engineering student learns about business or psychology, they can understand the human behavior better5. This will help them later when they work in a company team or become a manager. Secondly, the modern job market changes very fast today. If a person only knows one specific subject, it might be hard to find a new job if their industry goes down6. Therefore, having extra knowledge makes them more flexible and gives them more opportunities.
In conclusion, although focusing on one main subject helps students to pass difficult exams and become a specialist, I firmly believe that studying other subjects is more beneficial. It provides a wider knowledge and prepares them better for the real world.
